________________General Description

The MAX4524/MAX4525 are low-voltage, single-supply

CMOS analog switches configured as a 4-channel mul-

tiplexer/demultiplexer (MAX4524) and a double-

pole/double-throw (DPDT) switch (MAX4525). Both

have an inhibit input to simultaneously open all signal

paths.

These devices operate from a single supply of +2V to

+12V and are optimized for operation with +3V or +5V

supplies. On-resistance is 200

Ω with a +5V supply and

500

Ω with a +3V supply. Each switch can handle Rail-

to-Rail analog signals. The off-leakage current is only

2nA at +25°C or 20nA at +85°C.

All digital inputs have 0.8V to 2.4V logic thresholds,

ensuring TTL/CMOS-logic compatibility when using a

single +5V supply.
