NC = NO CONNECTION INSIDE PACKAGE. 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. 3.0V 0V MIN. POSITIVE INPUT PULSE 2.8V 3.0V MIN.
