| 3 | J | output | Output of the first AND gate, J = A·B. |
| 4 | K | output | Output of the second AND gate, K = C·D. |
| 5 | C | input | Input C of the second AND gate (K = C·D). |
| 6 | D | input | Input D of the second AND gate (K = C·D). |
| 7 | VSS | power_in | Negative supply / ground. |
| 8 | E | input | Input E of the third AND gate (L = E·F). |
| 9 | F | input | Input F of the third AND gate (L = E·F). |
| 10 | L | output | Output of the third AND gate, L = E·F. |
| 11 | M | output | Output of the fourth AND gate, M = G·H. |
| 12 | G | input | Input G of the fourth AND gate (M = G·H). |
| 13 | H | input | Input H of the fourth AND gate (M = G·H). |
| 14 | VDD | power_in | Positive supply voltage. |
