The MC74VHC1G02 / MC74VHC1GT02 is a an advanced high
speed CMOS 2−input NOR gate in tiny footprint packages. The
MC74VHC1G02 has CMOS−level input thresholds while the
MC74VHC1GT02 has TTL level 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.
