Overview: DATASHEET ISL55141, ISL55142, ISL55143
High-Speed 18V CMOS parators
ISL55141, ISL55142, ISL55143 integrated circuits are high-speed, wide input mon-mode range parators. They provide three-state window parators in a high voltage CMOS process (18V). Each parator 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 parator provide the test controller with qualification of a parator input into three states. The two output bits work with a separate user supply to establish VOH, VOL levels patibility with the system’s controller logic levels.
Fast propagation delay (9.5ns typical at ±50mV overdrive) makes this family patible with high-speed digital test systems. The 18V range enables the parator input to operate over a wide input range. Two references per input enable and three state digitalization of input with voltage swings of up to 13V mon 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). FN6230 Rev 4.
