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.

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.
