Low-Voltage, Single-Supply
Multiplexer and Switch
________________General Description
____________________________Features
ꢀ Tiny 10-Pin Thin QFN Package
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.
ꢀ Single-Supply Operation from +2V to +12V
ꢀ 200Ω On-Resistance with +5V Supply
ꢀ 500Ω On-Resistance with +3V Supply
ꢀ Guaranteed 8Ω On-Resistance Match at +5V
ꢀ Guaranteed 2nA Max On-Leakage at +5V
ꢀ TTL/CMOS-Logic Compatible
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.

TEMP RANGE
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V supply.
