MC74VHC373
Octal D−Type Latch
with 3−State Output
The MC74VHC373 is an advanced high speed CMOS octal latch
with 3−state output fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar Schottky
TTL while maintaining CMOS low power dissipation.
This 8−bit D−type latch is controlled by a latch enable input and an
output enable input. When the output enable input is high, the eight
outputs are in a high impedance state.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.
