The MC74VHC1GT02 is a single-gate 2-input NOR fabricated using a silicon-gate CMOS process. This internal circuit consists of multiple stages including a buffer output that provides high noise immunity and stable output. The device inputs are compatible with TTL type input thresholds and the outputs have full 5.0 V CMOS level output swings. The input protection circuitry on this device allows for overvoltage tolerance on the inputs allowing this 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 with high Operates under voltage power supply. The MC74VHC1GT02 input structure provides protection for applied voltages up to 5.5 V regardless of the supply voltage. So the MC74VHC1GT02 is used to interface 5 V circuits to 3 V circuits. The output structure also provides protection when VCC = 0V. These input and output structures help prevent device damage due to supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.
