General Description
The MAX4530/MAX4531/MAX4532 are low-voltage,
CMOS analog ICs configured as an 8-channel multiplexer (mux) (MAX4530), two 4-channel muxes
(MAX4531), and three single-pole/double-throw
switches (MAX4532). These devices are pin compatible
with the industry-standard 74HC4351/74HC4352/
74HC4353. All devices have two complementary
switch-enable inputs and address latching.
The MAX4530/MAX4531/MAX4532 operate from a single supply of +2V to +12V, or from dual supplies of
±2V to ±6V. On-resistance (150Ω max) is matched
between switches to 8Ω max. Each switch can handle
rail-to-rail analog signals. Off-leakage current is only
1nA at TA= +25°C and 50nA at TA= +85°C.
All digital inputs have 0.8V and 2.4V logic thresholds,
ensuring both TTL- and CMOS-logic compatibility when
using ±5V or a single +5V supply.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3: Guaranteed by design.
Note 4: ∆R
ON
= RON(max) - RON(min).
Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges, i.e., V
NO
= 3V to 0V and 0V to -3V.
Note 6: Leakage parameters are 100% tested at maximum-rated hot-operating temperature, and guaranteed by correlation at
T
A
= +25°C.
Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log V
COM
/ VNO,
V
COM
= output, VNO= input to off switch.
Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.

__________Applications Information
Power-Supply Considerations
Overview
The MAX4530/MAX4531/MAX4532 construction is typical of most CMOS analog switches. They have three
supply pins: V+, V-, and GND. V+ and V- 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 analog-signal
pin and both V+ and V-. One of these diodes conducts
if any analog signal exceeds V+ or V-. During normal
operation, these and other reverse-biased ESD diodes
leak, forming the only current drawn from V+ or V-.
Virtually all of 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+ or V- and the analog signal. This
means their leakages vary as the signal varies. The
difference in the two diode leakages to the V+ and Vpins 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. For this reason, both sides of a given switch can
show leakage currents of either the same or opposite
polarity.
The analog-signal paths and GND are not connected.
V+ and GND power the internal logic and logic-level
translators, and set both the input and output logic limits. The logic-level translators convert the logic levels
into switched V+ and V- signals to drive the analog signals’ gates. This drive signal is the only connection
between the logic supplies and signals and the analog
supplies. V+ and V- have ESD-protection diodes to
GND.
The logic-level thresholds are TTL/CMOS compatible
when V+ = +5V. As V+ rises, the threshold increases
slightly, so when V+ reaches +12V, the threshold is
about 3.1V—above the TTL guaranteed, high-level minimum of 2.8V, but still compatible with CMOS outputs.
Bipolar Supplies
The MAX4530/MAX4531/MAX4532 operate with bipolar
supplies between ±2.0V and ±6V. The V+ and V- supplies need not be symmetrical, but their sum cannot
exceed the +13V absolute maximum rating.
Single Supply
The MAX4530/MAX4531/MAX4532 operate from a single supply between +2V and +12V when V- is connected to GND. All of the bipolar precautions must be
observed. At room temperature, they actually work with
a single supply at, near, or below +1.7V, although as
supply voltage decreases, switch on-resistance and
switching times become very high.
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 in turning the switch on, but in turning it off. The offstate switch acts like a capacitor and passes higher
frequencies with less attenuation. At 10MHz, off isolation is about -65dB 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.
