SN7432N datasheet, a 14.1 KB PDF covering the quad 2-input positive OR gate in plastic DIP from the standard TTL line. It shows which pins carry each gate's inputs and output, plus supply pins and electrical limits. It is useful for quick gate testing with a logic probe, since any high input should drive a high output. When replacing the chip, check whether the board uses the standard, LS or HC family, because input thresholds and current draw differ.
