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 Ω 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.
