onsemi M74VHC1GT126DT1G

The MC74VHC1GT126 is a single gate noninverting 3−state 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 MC74VHC1GT126 requires the 3−state control input (OE) to be set Low to place the output into the high impedance state. 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 V CMOS logic to 5 V CMOS Logic or from 1.8 V CMOS logic to 3 V CMOS Logic while operating at the high−voltage power supply. The MC74VHC1GT126 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHC1GT126 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.
