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, CV_A and CV_B, for establishing
minimum 1-V_IH and maximum 0-V_IL 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
V_OH, V_OL 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 three state digitalization of input with voltage
swings of up to 13V common 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).

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details
on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish,
which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ISL55141, ISL55142, ISL55143. For more
information on MSL please see techbrief TB363.
