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
(6Ω max) is matched between switches to 1Ω max.
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.
