The MC74VHC1GT00 is a single gate 2-input NAND fabricated with silicon gate CMOS technology. The internal circuit is composed of multiple 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 VCMOS 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 whenvoltages up to 5.5 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 VCC = 0 V. These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.
