74LVC2G32
DUAL 2-INPUT OR GATE
Description
The 74LVC2G32 is a dual, two input OR gate. Both gates have push-
pull outputs designed for operation over a power supply range of
1.65V to 5.5V. The device is fully specified for partial power down
applications using I
OFF
. The I
OFF
circuitry disables the output,
preventing damaging current backflow when the device is powered
down. Each gate performs the positive Boolean function:

7. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device
operation should be within recommend values.
8. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could
cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
