TECHNICAL DATA
Quad 2-Input OR Gate
High-Speed Silicon-Gate CMOS
The IN74AC32 is identical in pinout to the LS/ALS32, HC/HCT32.
The device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALS outputs.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or
V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
