MC74VHCT573A
Octal D-Type Latch
with 3-State Output
The MC74VHCT573A 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 VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3 V to 5.0 V, because it
has full 5.0 V CMOS level output swings.
The VHCT573A input and output (when disabled) structures
provide protection when voltages between 0 V and 5.5 V are applied,
regardless of the supply voltage. These input and output structures
help prevent device destruction caused by supply
voltage−input/output voltage mismatch, battery backup, hot insertion,
etc.
