CASE 483

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 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.

The MC74VHC1GT00 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This

allows the MC74VHC1GT00 to be used to interface 5 V circuits to 3 V circuits. The output structures also provide protection when

battery backup, hot insertion, etc.
