MC74VHCT14A
Hex Schmitt Inverter
The MC74VHCT14A is an advanced high speed CMOS Schmitt
inverter fabricated with silicon gate CMOS technology. It achieves
high speed operation similar to equivalent Bipolar Schottky TTL
while maintaining CMOS low power dissipation.
Pin configuration and function are the same as the
MC74VHCT04A, but the inputs have hysteresis and, with its Schmitt
trigger function, the VHCT14A can be used as a line receiver which
will receive slow input signals.
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 VHCT14A input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage.
The output structures also provide protection when V_CC = 0 V. These
input and output structures help prevent device destruction caused by
supply voltage − input/output voltage mismatch, battery backup, hot
insertion, etc.
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.
