| 3 | 2A | input | Input of gate 2; inputs are diode-clamped and tolerate up to 5.25 V, with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 4 | 2Y | output | Open-collector output of gate 2 with a rated off-state voltage of 30 V and a maximum sink current of 40 mA. |
| 5 | 3A | input | Input of gate 3; inputs are diode-clamped and tolerate up to 5.25 V, with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 6 | 3Y | output | Open-collector output of gate 3 with a rated off-state voltage of 30 V and a maximum sink current of 40 mA. |
| 7 | GND | power_in | Ground pin; all device voltages are referenced to GND. |
| 8 | 4Y | output | Open-collector output of gate 4 with a rated off-state voltage of 30 V and a maximum sink current of 40 mA. |
| 9 | 4A | input | Input of gate 4; inputs are diode-clamped and tolerate up to 5.25 V, with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 10 | 5Y | output | Open-collector output of gate 5 with a rated off-state voltage of 30 V and a maximum sink current of 40 mA. |
| 11 | 5A | input | Input of gate 5; inputs are diode-clamped and tolerate up to 5.25 V, with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 12 | 6Y | output | Open-collector output of gate 6 with a rated off-state voltage of 30 V and a maximum sink current of 40 mA. |
| 13 | 6A | input | Input of gate 6; inputs are diode-clamped and tolerate up to 5.25 V, with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 14 | VCC | power_in | Supply pin; recommended operating supply is 4.75 V to 5.25 V (5 V nominal), with a 0.1 µF bypass capacitor placed as close to the pin as possible. |
