Application Information
The ISL55100A provides Quad pin drivers and Quad dual
level comparator receivers in a small footprint. The four
channels may be used as bidirectional or split channels.
Drivers have per channel level, data, and high impedance
controls, while comparators have per channel high and low
threshold levels.

Receiver Features
The receivers are four independent window comparators that
feature high output current capability, and user defined high
and low output levels to interface with a wide variety of logic
families. Each receiver, comprises two comparators and each
comparator has an independent threshold level input, making
it easy to implement window comparator functions. The CVA
and CVB pins set the threshold levels of the A and B
comparators respectively. COMP HIGH and COMP LOW set
all the comparator output levels, and COMP HIGH must be
