74AHC32
QUADRUPLE 2-INPUT OR GATES
Description
The 74AHC32 provides provides four independent 2-input OR gates
with standard push-pull outputs. The device is designed for operation
with a power supply range of 2.0V to 5.5V. The inputs are tolerant to
5.5V allowing this device to be used in a mixed voltage environment.
The gates perform the Boolean function:
