MC74VHC1GT04

Inverting Buffer /

CMOS Logic Level Shifter

with LSTTL–Compatible Inputs

The MC74VHC1GT04 is a single gate inverting buffer fabricated

with silicon gate CMOS technology. It achieves high speed operation

similar to equivalent Bipolar Schottky TTL while maintaining CMOS

low power dissipation.

The internal circuit is composed of three stages, including a buffer

output which provides high noise immunity and stable output.

The device input is compatible with TTL–type input thresholds and

the output has a full 5V CMOS level output swing. The input

protection circuitry on this device allows overvoltage tolerance on the

input, allowing the device to be used as a logic–level translator from

3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to

3.0V CMOS Logic while operating at the high–voltage power supply.

The MC74VHC1GT04 input structure provides protection when

voltages up to 7V are applied, regardless of the supply voltage. This

allows the MC74VHC1GT04 to be used to interface 5V circuits to 3V

circuits. The output structures also provide protection when VCC = 0V.

These input and output structures help prevent device destruction

caused by supply voltage – input/output voltage mismatch, battery

backup, hot insertion, etc.
