Overview
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.
