The MC74VHC1G03 / MC74VHC1GT03 is a 2−input NOR Gate

with an open drain output in tiny footprint packages.

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.
