MAXIM MAX4524L, MAX4525L User Manual

General Description

The MAX4524L/MAX4525L are low-voltage, single-sup­ply CMOS analog switches configured as a 4-channel
multiplexer/demultiplexer (MAX4524L) and a double­pole/double-throw (DPDT) switch (MAX4525L). The
MAX4524L/MAX4525L have an inhibit input to simulta­neously open all switches.

These devices operate from a single supply of +2V to
+12V. They are optimized for operation with a +12V sup­ply. The on-resistance is 100Ω with a +12V supply. Each
switch can handle Rail-to-Rail analog signals. Off-leakage
current measures only 2nA at +25°C. All digital inputs
have 0.8V to 2.0V logic thresholds to ensure TTL/CMOS­logic compatibility when using a +12V supply.

Applications

Audio and Video Signal Routing

(Notes 2, 3)

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.
