MC74VHC1GT00
2-Input NAND Gate /
CMOS Logic Level Shifter
with LSTTL–Compatible Inputs
The MC74VHC1GT00 is a single gate 2–input NAND 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 MC74VHC1GT00 input structure provides protection when
voltages up to 7V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT00 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.
