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
500
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.

... Information 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 ...
