General Description

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

(6

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

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.
