August 13, 2015 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. Features 18V I/O Range 65MHz Operation 9.5ns Typical Propagation Delay Programmable Input Thresholds User Defined Comparator OutputLlevels Common-Mode Range Includes Negative Rails Small Footprints in QFN Packages Power-Down Current <10ВµA Pb-Free (RoHS compliant) Fast propagation delay (9.5ns typical at В±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 digitalization of input with voltage
swings of up to 13V common mode. The operating
frequency of these devices is typically 65MHz. Applications Burn in ATE Low Cost ATE Fast Supervisory Power Control Instrumentation High voltage CMOS process makes these devices ideal for …
