Diodes 74LVC08A User Manual
A
Description
The 74LVC08A provides four independent 2-input AND gates. The
device is designed for operation with a power supply range of 1.65V
to 5.5V. The inputs are tolerant to 5.5V allowing this device to be
used in a mixed voltage environment. The device is fully specified for
partial power down applications using IOFF. The IOFF circuitry
disables the output preventing damaging current backflow when the
device is powered down.
The gates perform the positive Boolean function:
BAY •=
or
BAY +=
