MC74VHCT50A
Noninverting Buffer /
CMOS Logic Level Shifter
with LSTTL−Compatible Inputs
silicon gate CMOS technology. It achieves high speed operation
similar to equivalent Bipolar Schottky TTL while maintaining CMOS
low power dissipation.
output which provides high noise immunity and stable output.
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
3.0 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 high−voltage power
supply.
voltages up to 7 V are applied, regardless of the supply voltage. This
allows the MC74VHCT50A to be used to interface 5 V circuits to 3 V
circuits. The output structures also provide protection when
