How to · reading it

How to read the 74HC32 pinout

01
Find pin 1
One end of the chip has a half-circle notch or a dot; with the notch facing up, the top-left pin is pin 1.
02
Count counter-clockwise
Count counter-clockwise from pin 1: go down the left side first, then up the right side from the bottom.
03
Check the table below
Look up each pin's function by number in the table below; power/ground are color-coded, and alternate-function signals are in parentheses.

FAQ

Do the 74HC32 and 74HC08 have the same pinout?

The pin layout is identical; the only difference is the gate logic: the 32 is an OR gate, the 08 is an AND gate.

Can I make a 4-input gate from 2-input ones?

Yes, cascade multiple gates: e.g. feed the outputs of two ORs into a third OR to make a 4-input OR.

Data source
