| 3 | A2 | input | Data input 2 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 4 | A3 | input | Data input 3 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 5 | A4 | input | Data input 4 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 6 | A5 | input | Data input 5 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 7 | A6 | input | Data input 6 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 8 | A7 | input | Data input 7 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 9 | A8 | input | Data input 8 with Schmitt-trigger hysteresis, 0 to 5.5 V input range. |
| 10 | GND | power_in | Ground (0 V) supply pin. |
| 11 | Y8 | tri_state | 3-state output 8, high impedance when G is HIGH; IOH/IOL up to ±8 mA at VCC 4.5 V. |
