MAX4736
0.6Ω, Low-Voltage, Single-Supply, Dual SPDT
Analog Switch
The MAX4736 is a low on-resistance, low-voltage, dual
single-pole/double throw (SPDT) analog switch that oper-
ates from a single 1.6V to 4.2V supply. This device has
fast switching speeds (t
ON
= 25ns, t
OFF
= 20ns max),
handles rail-to-rail analog signals, and consumes less
than 4μW of quiescent power. The MAX4736 has break-
before-make switching.
When powered from a 3V supply, the MAX4736 features
low 0.6Ω on-resistance (R
ON
), with 0.1Ω R
ON
matching
and 0.05Ω R
ON
flatness. The digital logic input is 1.8V
CMOS compatible when using a single 3V supply.
The MAX4736 has one normally open (NO) switch and
one normally closed (NC) switch, and is available in
12-pin TQFN (3mm x 3mm), 10-pin μMAX, and 10-pin
μDFN (2mm x 2mm) packages.

Note 1:
Signals on COM_, NO_, or NC_ exceeding V+ or GND are clamped by internal diodes. Limit forward current to maximum
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.
