Analog Switches
General Description
The MAX4751/MAX4752/MAX4753 are low on-resistance,
low-voltage, quad, single-pole/single-throw (SPST) analog
switches that operate from a single +1.6V to +3.6V sup-
ply. These devices have fast switching speeds (t
ON
=
30ns, t
OFF
= 25ns), handle rail-to-rail analog signals, and
consume less than 1µW of quiescent power. The
MAX4753 has break-before-make switching.
When powered from a +3V supply, the MAX4751/
MAX4752/MAX4753 feature low 0.9Ω (max) on-resis-
tance (R
ON
), with 0.12Ω (max) R
ON
matching and 0.1Ω
(max) R
ON
flatness. The digital input is 1.8V CMOS
compatible when using a single +3V supply.
The MAX4751 has four normally open (NO) switches,
the MAX4752 has four normally closed (NC) switches,
and the MAX4753 has two NO and two NC switches.
The MAX4751/MAX4752/MAX4753 are available in
3mm
3mm, 16-pin QFN and 14-pin TSSOP packages.

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