Force-Sense Switches
General Description
Features
The MAX4554/MAX4555/MAX4556 are CMOS analog ICs
configured as force-sense switches for Kelvin sensing in
automated test equipment (ATE). Each part contains
high-current, low-resistance switches for forcing current,
and higher resistance switches for sensing a voltage or
switching guard signals. The MAX4554 contains two
force switches, two sense switches, and two guard
switches configured as two triple-pole/single-throw
(3PST) normally open (NO) switches. The MAX4555 con-
tains four independent single-pole/single-throw (SPST)
normally closed (NC) switches, two force switches, and
two sense switches. The MAX4556 contains three inde-
pendent single-pole/double-throw (SPDT) switches, of
which one is a force switch and two are sense switches.
These devices operate from a single supply of +9V to
+40V or dual supplies of ±4.5V to ±20V. On-resistance
(6max) is matched between switches to 1max.
Each switch can handle Rail-to-Rail® analog signals.
The off-leakage current is only 0.25nA at +25°C and
2.5nA at +85°C. The MAX4554 is also fully specified for
+20V and -10V operation.
All digital inputs have +0.8V and +2.4V logic thresh-
olds, ensuring both TTL- and CMOS-logic compatibility.

Note 1: Signals on analog or digital pins exceeding V+ or V- 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.
