DESCRIPTION
74AUC1G32
The 74AUC1G32 is a high-performance, low-power,
low-voltage, Si-gate CMOS device.
Schmitt-trigger action at all inputs makes the circuit
tolerant for slower input rise and fall time.
This device is fully specified for partial power-down
applications using I
off
. The I
off
circuitry disables the output,
preventing the damaging current backflow through the
device when it is powered down.
The 74AUC1G32 provides the single 2-input OR function.
