PRODUCT DESCRIPTION
The AD53042 is an ultrahigh speed window comparator
with latch. It uses a high speed monolithic process to provide
high dc accuracy without sacrificing input voltage range.
On-chip connection of the common input eliminates the
contributions of a second bonding pad and package pin to
the input capacitance, resulting in a maximum input
capacitance of 2 pF.
The AD53042 employs a high precision differential input
stage with a common mode range of 9 V. Its complementary
digital outputs are fully ECL-compatible. The output stage is
capable of driving a 50
line terminated to –2 V. The device
also provides a latch function, allowing operation in track-hold
mode and can also be used to generate hysteresis.
