The MC74VHC1GT125 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 MC74VHC1GT125 requires the 3−state control input (OE) to be set High to place the output into the high impedance state.

MC74VHC1GT125 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 MC74VHC1GT125 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 MC74VHC1GT125 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHC1GT125 to be used to interface 5 V circuits to 3 V 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.
