________________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 200Ω with a +5V supply and

500Ω 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.

PAGE 7
Low-Voltage, Single-Supply Multiplexer and Switch Power-Supply Considerations The MAX4524/MAX4525’s construction is typical of most CMOS analog switches. They have two supply pins: V+ and GND. V+ and 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 analog signal pin and both V+ and GND. If any analog signal exceeds V+ or GND, one of these diodes will conduct.
PAGE 8
MAX4524/MAX4525 Low-Voltage, Single-Supply Multiplexer and Switch There is no connection between the analog signal paths and GND. 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 GND signals to drive the gates of the analog signals. This drive signal is the only connection between the logic supplies (and signals) and the analog supplies.
