DATASHEET ISL55141, ISL55142, ISL55143 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, CVA and CVB, for establishing minimum 1-VIH and maximum 0-VIL voltage levels. These 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 VOH, VOL levels compatibility with the system’s controller 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 t...
