Octal D-Type Flip-Flop
with 3-State Output
The MC74VHCT374A is an advanced high speed CMOS octal
flip–flop 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 flip–flop is controlled by a clock 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 VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3V to 5.0V, because it has
full 5V CMOS level output swings.
The VHCT374A input and output (when disabled) structures
provide protection when voltages between 0V and 5.5V 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.
