MAXIM MAX4617, MAX4618, MAX4619 Technical data

________________General Description

The MAX4617/MAX4618/MAX4619 are high-speed, low­voltage, CMOS analog ICs configured as an 8-channel
multiplexer (MAX4617), two 4-channel multiplexers
(MAX4618), and three single-pole/double-throw (SPDT)
switches (MAX4619).

These CMOS devices can operate continuously with a
+2V to +5.5V single supply. Each switch can handle
Rail-to-Rail®analog signals. The off-leakage current is
only 1nA at TA= +25°C and 10nA at TA= +85°C.

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

__________Applications Information

Power-Supply Considerations

Overview

The MAX4617/MAX4618/MAX4619 construction is typi­cal of most CMOS analog switches. They have two sup­ply pins: VCCand GND. VCCand GND are used to drive
the internal CMOS switches and set the limits of the ana­log voltage on any switch. Reverse ESD-protection
diodes are internally connected between each analog­signal pin and both VCCand GND. If any analog signal
exceeds VCCor GND, one of these diodes conducts.
During normal operation, these and other reverse­biased ESD diodes leak, forming the only current drawn
from VCCor GND.

Virtually all the analog leakage current comes from 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

CC

or GND and the analog signal. This means their

leakages will vary as the signal varies. The

difference

in
the two diode leakages to the VCCand GND pins con­stitutes the analog-signal-path leakage current. All ana­log leakage current flows between each pin and one of
the supply terminals, not to the other switch terminal.
This is why both sides of a given switch can show leak­age currents of either the same or opposite polarity.

VCCand GND power the internal logic and set the input
logic limits. Logic inputs have ESD-protection diodes to
ground.

Note: Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well

in both directions.

Digital Enable Input. Normally connect to GND. Can be driven
to logic high to set all switches off.

High-Speed, Low-Voltage, CMOS Analog

Multiplexers/Switches

_______________________________________________________________________________________ 9

The logic-level thresholds are TTL/CMOS compatible
when VCCis +5V. As VCCrises, the threshold increas­es; as VCCfalls, the threshold decreases. For example,
when VCC= +3V the guaranteed minimum logic-high
threshold decreases to 2.0V

Power Supply

These devices operate from a single supply between
+2.5V and +5.5V. All of the bipolar precautions must be
observed. At room temperature, they actually “work”
with a single supply near or below +2V, although as
supply voltage decreases, switch on-resistance
becomes very high.

Overvoltage Protection

Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi­mum ratings because stresses beyond the listed rat­ings can cause permanent damage to the devices.
Always sequence VCCon first, followed by the logic
inputs and analog signals. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with the supply pins for overvoltage protection
(Figure 1).

Adding diodes reduces the analog-signal range to one
diode drop below VCCand one diode drop above
GND, but does not affect the devices’ low switch resis­tance and low leakage characteristics. Device opera­tion is unchanged, and the difference between V

CC

and GND should not exceed 6V. These protection
diodes are not recommended if signal levels must
extend to ground.

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 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 -50dB in 50Ω systems, becoming worse (approx­imately 20dB per decade) as frequency increases.
Higher circuit impedances also degrade off-isolation.
Adjacent channel attenuation is about 3dB above that
of a bare IC socket and is entirely due to capacitive
coupling.

Pin Nomenclature

The MAX4617/MAX4618/MAX4619 are pin compatible
with the industry-standard 74HC4051/74HC4052/
74HC4053 and the MAX4581/MAX4582/MAX4583. In
single-supply applications, they function identically and
have identical logic diagrams, although these parts dif­fer electrically.

The pin designations and logic diagrams in this data
sheet conform to the original 1972 specifications pub­lished by RCA for the CD4051/CD4052/CD4053. These
designations differ from the standard Maxim switch and
mux designations found on other Maxim data sheets
(including the MAX4051/MAX4052/MAX4053) and may
cause confusion. Designers who feel more comfortable
with Maxim’s standard designations are advised that
the pin designations and logic diagrams on the
MAX4051/MAX4052/MAX4053 data sheet may be freely
applied to the MAX4617/MAX4618/MAX4619.
