Low-Voltage, Single-Supply Analog
Multiplexers/Switches
General Description
The MAX4524L/MAX4525L are low-voltage, single-sup-
ply CMOS analog switches configured as a 4-channel
multiplexer/demultiplexer (MAX4524L) and a double-
pole/double-throw (DPDT) switch (MAX4525L). The
MAX4524L/MAX4525L have an inhibit input to simulta-
neously open all switches.
These devices operate from a single supply of +2V to
+12V. They are optimized for operation with a +12V sup-
ply. 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/CMOS-
logic compatibility when using a +12V supply.

Note 1:
Voltages exceeding V+ or GND on any signal terminal are clamped by internal diodes. Limit forward-diode current to maxi-
mum current rating.
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.

Note 4:
Note 5:
The TDFN package is production tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
The algebraic convention used in this data sheet is where the most negative value is a minimum column.
∆R
ON
= R

.
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 6:
Leakage parameters are 100% tested at maximum-rated hot operating temperature and guaranteed by design at T
A
= +25°C.
Note 7:
Guaranteed by design, not production tested.
