The MC74VHC1G50 / MC74VHC1GT50 is an advanced high

speed CMOS buffer in tiny footprint packages. The MC74VHC1G50

has CMOS level input thresholds while the MC74VHC1GT50 has

TTL level input thresholds.

The input structures provide protection when voltages up to 5.5 V

are applied, regardless of the supply voltage. This allows the device to

be used to interface 5 V circuits to 3 V circuits. Some output structures

also provide protection when VCC = 0 V and when the output voltage

exceeds VCC. These input and output structures help prevent device

destruction caused by supply voltage − input/output voltage mismatch,

battery backup, hot insertion, etc.
