MAX4554/MAX4555/MAX4556 19-1358 Rev 0 4/98 Force-Sense Switches General Description Features The MAX4554/MAX4555/MAX4556 are CMOS analog ICs 6 Force Signal Paths (15V Supplies) configured as force-sense switches for Kelvin sensing in 1 Force Signal Matching (15V Supplies) automated test equipment (ATE). Each part contains 60 Sense-Guard Signal Paths (15V Supplies) high-current, low-resistance switches for forcing current, and higher resistance switches for sensing a voltage or 8 Sense-Guard Signal Matching (15V Supplies) switching guard signals. The MAX4554 contains two Rail-to-Rail Signal Handling force switches, two sense switches, and two guard Break-Before-Make Switching (MAX4556) switches configured as two triple-pole/single-throw (3PST) normally open (NO) switches. The MAX4555 con- t and t = 275ns (15V Supplies) ON OFF tains four independent single-pole/single-throw (SPST) normally closed (NC) switches, two force switches, and Low 1A Power Consumption two sense switches. The MAX4556 contains three inde- >2kV ESD Protection per Method 3015.7 pendent single-pole/double-throw (SPDT) switches, of which one is a force switch and two are sense switches. TTL/CMOS-Compatible Inputs These devices operate from a single supply of +9V to +40V or dual supplies of 4.5V to 20V. On-resistance Ordering Information (6 max) is matched between switches to 1 max. Each switch can handle Rail-to-Rail analog signals. PART TEMP. RANGE PIN-PACKAGE The off-leakage current is only 0.25nA at +25C and MAX4554CPE 0C to +70C 16 Plastic DIP 2.5nA at +85C.

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.
