DATASHEET ISL55141, ISL55142, ISL55143 FN6230 Rev 4.00 High-Speed 18V CMOS Comparators August 13, 2015 ISL55141, ISL55142, ISL55143 integrated circuits are Features high-speed, wide input common-mode range comparators. 18V I/O Range They provide three-state window comparators in a high voltage CMOS process (18V). Each comparator has dual 65MHz Operation receive thresholds, CV and CV , for establishing A B 9.5ns Typical Propagation Delay minimum 1-V and maximum 0-V voltage levels. These IH IL Programmable Input Thresholds devices can accept inputs from a number of logic families, such as TTL, ECL, CMOS, LVCMOS, LVDS and CML. Two User Defined Comparator OutputLlevels bits of output per comparator provide the test controller with Common-Mode Range Includes Negative Rails qualification of a comparator input into three states. The two output bits work with a separate user supply to establish Small Footprints in QFN Packages V , V levels compatibility with the systems controller OH OL Power-Down Current <10A logic levels. Pb-Free (RoHS compliant) Fast propagation delay (9.5ns typical at 50mV overdrive) makes this family compatible with high-speed digital test Applications systems. The 18V range enables the comparator input to Burn in ATE operate over a wide input range. Two references per input enable and three state digitalization of input with voltage Low Cost ATE swings of up to 13V common mode. The operating Fast Supervisory Power Control frequency of these devices is typically 65MHz. Instrumentation 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).
