7432 is a 14 pin IC is an OR gate.
Pin Description
1 A Input Gate 1
2 B Input Gate 1
3 Y Output Gate 1
4 A Input Gate 2
5 B Input Gate 2
6 Y Output Gate 2
7 Ground
8 Y Output Gate 3
9 A Input Gate 3
10 B Input Gate 3
11 Y Output Gate 4
12 A Input Gate 4
13 B Input Gate 4
14 Positive Supply
So 3, 6, 8, 11 are output pins for OR gate.
