Noninverting Buffer /
CMOS Logic Level Shifter
TTLCompatible Inputs
The MC74VHC1GT50 is a single gate noninverting 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 TTLtype input thresholds and
the output has a full 5.0 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 logiclevel translator from
3.0 V CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to
3.0 V CMOS Logic while operating at the highvoltage power supply.
The MC74VHC1GT50 input structure provides protection when
voltages up to 7.0 V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT50 to be used to interface high voltage to
low voltage circuits. 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.
