Maxim MAX4553ESE, MAX4553EPE, MAX4553CPE, MAX4553CEE, MAX4553C-D Datasheet

General Description

The MAX4551/MAX4552/MAX4553 are quad, low-volt­age, single-pole/single-throw (SPST) analog switches.
Each switch is protected against ±15kV electrostatic
discharge (ESD) shocks, without latchup or damage.
On-resistance (100Ω max) is matched between switch­es to 4Ω max, and is flat (8Ω max) over the specified
signal range. Each switch can handle Rail-to-Rail®ana­log signals. The off-leakage current is only 1nA at
+25°C and 10nA at +85°C.

The MAX4551 has four normally closed (NC) switches,
and the MAX4552 has four normally open (NO) switch­es. The MAX4553 has two NC and two NO switches.

These CMOS switches can operate with dual power
supplies ranging from ±2V to ±6V or a single supply
between +2V and +12V. They are fully specified for sin­gle +2.7V operation.

All digital inputs have +0.8V and +2.4V logic thresh­olds, ensuring TTL/CMOS-logic compatibility when
using ±5V or a single +5V supply.

MAX4551/MAX4552/MAX4553

±15kV ESD Protection

The MAX4551/MAX4552/MAX4553 are ±15kV ESD-pro­tected according to IEC 1000-4-2 at their NC/NO pins.
To accomplish this, bidirectional SCRs are included on­chip between these pins and the GND pin. In normal
operation, these SCRs are off and have negligible
effect on the performance of the switches. When there
is an ESD strike at these pins, however, the voltages at
these pins go Beyond-the-Rails™ and cause the corre­sponding SCR(s) to turn on in a few nanoseconds and
bypass the surge safely to ground. This method is
superior to using diode clamps to the supplies because
unless the supplies are very carefully decoupled
through low ESR capacitors, the ESD current through
the diode clamp could cause a significant spike in the
supplies. This may damage or compromise the reliabili­ty of any other chip powered by those same supplies.

In the MAX4551/MAX4552/MAX4553, there are diodes
to the supplies in addition to the SCRs at the NC/NO
pins, but there is a resistance in series with these
diodes to limit the current into the supplies during an
ESD strike. The diodes are present to protect these
pins from overvoltages that are not as a result of ESD
strikes like those that may occur due to improper
power-supply sequencing.

Once the SCR turns on because of an ESD strike, it
continues to be on until the current through it falls
below its “holding current.” The holding current is typi­cally 110mA in the positive direction (current flowing
into the NC/NO pin) and 95mA in the negative direction
at room temperature (see SCR Holding Current vs.
Temperature in the

Typical Operating Characteristics

).
The system should be designed such that any sources
connected to these pins are current limited to a value
below these to make sure the SCR turns off when the
ESD event gets over to resume normal operation. Also,
keep in mind that the holding current varies significant­ly with temperature. At +85°C, which represents the
worst case, the holding currents drop to 70mA and
65mA in the positive and negative directions respec­tively. Since these are typical numbers, to get guaran­teed turn-off of the SCRs under all conditions, the
sources connected to these pins should be current lim­ited to not more than half these values. When the SCR
is latched, the voltage across it is about ±3V, depend­ing on the polarity of the pin current. The supply volt­ages do not affect the holding currents appreciably.
The sources connected to the COM side of the switches

do not need to be current limited since the switches are
made to turn off internally when the corresponding
SCR(s) get latched.

Even though most of the ESD current flows to GND
through the SCRs, a small portion of it goes into the
supplies. Therefore, it is a good idea to bypass the
supply pins with 100nF capacitors directly to the
ground plane.

ESD protection can be tested in various ways. Trans­mitter outputs and receiver inputs are characterized for
protection to the following:

• ±15kV using the Human Body Model

• ±8kV using the Contact Discharge method speci­fied in IEC 1000-4-2 (formerly IEC 801-2)

• ±15kV using the Air-Gap Discharge method speci­fied in IEC 1000-4-2 (formerly IEC 801-2).

ESD Test Conditions

Contact Maxim for a reliability report that documents
test setup, methodology, and results.

Human Body Model

Figure 8 shows the Human Body Model, and Figure 9
shows the current waveform it generates when dis­charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter­est, which is then discharged into the test device
through a 1.5kΩ resistor.

IEC 1000-4-2

The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not specifi­cally refer to integrated circuits. The MAX4551/MAX4552/
MAX4553 enable the design of equipment that meets
Level 4 (the highest level) of IEC 1000-4-2, without
additional ESD protection components.

The major difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2. Because series resistance is
lower in the IEC 1000-4-2 ESD test model (Figure 10),
the ESD withstand voltage measured to this standard
is generally lower than that measured using the
Human Body Model. Figure 11 shows the current
waveform for the ±8kV IEC 1000-4-2 Level 4 ESD
Contact Discharge test.

The Air-Gap test involves approaching the device with
a charged probe. The Contact Discharge method
connects the probe to the device before the probe is
energized.

Power-Supply Considerations

Overview

The MAX4551/MAX4552/MAX4553 construction is typi­cal of most CMOS analog switches. They have three
supply pins: V+, V-, and GND. V+ and V- are used to
drive the internal CMOS switches, and they set the lim­its of the analog voltage on any switch. Reverse ESD­protection diodes are internally connected between
each analog-signal pin and both V+ and V-. If any ana­log signal exceeds V+ or V-, one of these diodes con­ducts. During normal operation these reverse-biased
ESD diodes leak, forming the only current drawn from
V+ or V-.

Virtually all the analog leakage current is through the
ESD diodes. Although the ESD diodes on a given sig­nal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by
either V+ or V- and the analog signal. This means their
leakages vary as the signal varies. The

difference

in the
two diode leakages from the signal path to the V+ and
V- pins constitutes the analog-signal-path leakage cur­rent. All analog leakage current flows to the supply ter­minals, not to the other switch terminal. This explains
how both sides of a given switch can show leakage
currents of the same or opposite polarity.

The analog signal paths consist of an N-channel and P­channel MOSFET with their sources and drains paral­leled, and their gates driven out of phase to V+ and V­by the logic-level translators.

V+ and GND power the internal logic and logic-level
translators, and set the input logic thresholds. The
logic-level translators convert the logic levels to
switched V+ and V- signals, to drive the gates of the
analog switches. This drive signal is the only connec­tion between the logic supplies and the analog sup­plies. V+ and V- have ESD-protection diodes to GND.
The logic-level inputs and output have ESD protection
to V+ and to GND.

Increasing V- has no effect on the logic-level thresh­olds, but it does increase the drive to the P-channel
switches, reducing their on-resistance. V- also sets the
negative limit of the analog signal voltage.

The logic-level thresholds are CMOS/TTL compatible
when V+ = +5V. The threshold increases slightly as V+
is raised, and when V+ reaches +12V, the level thresh­old is about 3.1V. This is above the TTL output high­level minimum of 2.8V, but still compatible with CMOS
outputs.

Bipolar Supplies

The MAX4551/MAX4552/MAX4553 operate with bipolar
supplies between ±2V and ±6V. The V+ and V- sup­plies need not be symmetrical, but their sum cannot
exceed the absolute maximum rating of 13.0V. Do not

connect the MAX4551/MAX4552/MAX4553 V+ to +3V,
and then connect the logic-level-input pins to TTL
logic-level signals. TTL logic-level outputs in excess
of the absolute maximum ratings can damage the
part and/or external circuits.

Caution: The absolute maximum V+ to V- differential

voltage is 13.0V. Typical ±6V or 12V supplies with
±10% tolerances can be as high as 13.2V. This voltage
can damage the MAX4551/MAX4552/MAX4553. Even
±5% tolerance supplies may have overshoot or noise
spikes that exceed 13.0V.

Single Supply

The MAX4551/MAX4552/MAX4553 operate from a
single supply between +2V and +12V when V- is con­nected to GND. All of the bipolar precautions must be
observed.

High-Frequency Performance

In 50Ω systems, signal response is reasonably flat up
to 50MHz (see

Typical Operating Characteristics

).
Above 20MHz, the on-response has several minor
peaks that are highly layout-dependent. The problem
with high-frequency operation is not turning the switch
on, but turning it off. The off-state switch acts like a
capacitor and passes higher frequencies with less
attenuation. At 10MHz, off-isolation is about -52dB in
50Ω systems, becoming worse (approximately 20dB
per decade) as frequency increases. Higher circuit
impedances also make off-isolation worse. Adjacent
channel attenuation is about 3dB above that of a bare
IC socket, and is due entirely to capacitive coupling.
