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, CVAand CVB, for establishing minimum 1-VIHand 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, VOLlevels compatibility with the system’s controller logic levels.
