SINGLE 2-INPUT OR GATE

DESCRIPTION

The UTC U74VHC1GT32 is a single 2−input OR Gate in tiny

footprint packages. The U74VHC1GT32 has CMOS−level input

thresholds while the U74VHC1GT32 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 5V circuits to 3V circuits. Some output

structures also provide protection when VCC=0V 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.

FEATURES

* Operate from 2V to 5.5V

* Source/Sink 8 mA at 3.0V
