| 3 | A | input | Input of buffer A, protected by CMOS input protection network; maximum input current 1 µA at 18 V over temperature. |
| 4 | G | output | True (non-inverted) output of buffer B (G=B), with balanced source and sink current drive. |
| 5 | H | output | Complement (inverted) output of buffer B (H=B̄), with balanced source and sink current drive. |
| 6 | B | input | Input of buffer B, protected by CMOS input protection network; input voltage range -0.5 V to VDD+0.5 V. |
| 7 | VSS | power_in | Ground / negative supply terminal; all voltages are referenced to VSS. |
| 8 | K | output | True (non-inverted) output of buffer C (K=C), with balanced source and sink current drive. |
| 9 | L | output | Complement (inverted) output of buffer C (L=C̄), with balanced source and sink current drive. |
| 10 | C | input | Input of buffer C, protected by CMOS input protection network; input voltage range -0.5 V to VDD+0.5 V. |
| 11 | M | output | True (non-inverted) output of buffer D (M=D), with balanced source and sink current drive. |
