High-Speed 18V CMOS Comparators

ISL55141, ISL55142, ISL55143 integrated circuits are

high-speed, wide input common-mode range comparators.

They provide three-state window comparators in a high

voltage CMOS process (18V). Each comparator has dual

receive thresholds, CV

minimum 1-V

devices can accept inputs from a number of logic families,

such as TTL, ECL, CMOS, LVCMOS, LVDS and CML. Two

bits of output per comparator provide the test controller with

qualification of a comparator input into three states. The two

output bits work with a separate user supply to establish

logic levels.

Fast propagation delay (9.5ns typical at ±50mV overdrive)

makes this family compatible with high-speed digital test

systems. The 18V range enables the comparator input to

operate over a wide input range. Two references per input

enable and three state digitization of input with voltage

swings of up to 13V common mode. The operating

frequency of these devices is typically 65MHz.

High voltage CMOS process makes these devices ideal for

large voltage swing applications, such as special test

voltages levels associated with Flash devices or power

supervision applications and may avoid the need for test bus

isolation relay(s).
