描述 Description

The MC74VHC1GT50 is a single gate noninverting buffer fabricated with 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 compatible with low threshold input thresholds and the output has a full 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 1.65 V logic to 5.5V CMOS The MC74VHC1GT50 input structure provides protection for input voltages up to 7V , regardless of the supply voltage. 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.
