General Description

The MAX4530/MAX4531/MAX4532 are low-voltage,

CMOS analog ICs configured as an 8-channel multi-

plexer (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 sin-

gle 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 T

= +25°C and 50nA at T

= +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.

Low-Voltage, CMOS Analog Multiplexers/Switches with Enable Inputs and Address Latching 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-.
