The MC74VHC1GT04 is a single inverting buffer fabricated in silicon gate CMOS technology. It achieves high speed operation 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 has low input threshold and the output has a full 5V CMOS level output swing. The input protection circuitry on this device is overvoltage tolerant, allowing the device to be used as a logic-level translator.The MC74VHC1GT04 input structure provides protection when voltages up to 5.5V are applied, regardless of the supply voltage, allowing the the part to be used to interface 1.8/3.3V 3/5V 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.
