MC74VHC1GT14
Schmitt−Trigger Inverter /
CMOS Logic Level Shifter
LSTTL−Compatible Inputs
The MC74VHC1GT14 is a single gate CMOS Schmitt−trigger
inverter fabricated with silicon gate CMOS technology. It achieves
high speed operation similar to equivalent Bipolar Schottky TTL
while maintaining CMOS low power dissipation.

MARKING
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 5 V 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 V
CMOS logic to 5 V CMOS Logic or from 1.8 V CMOS logic to 3 V
CMOS Logic while operating at the high−voltage power supply.
The MC74VHC1GT14 input structure provides protection when
voltages up to 7 V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT14 to be used to interface 5 V circuits to 3 V

These input and output structures help prevent device destruction
caused by supply voltage − input/output voltage mismatch, battery
backup, hot insertion, etc. The MC74VHC1GT14 can be used to
enhance noise immunity or to square up slowly changing waveforms.
