| 5 | A3 | input | Data input A3, inverted to Y3 when enabled. |
| 6 | A4 | input | Data input A4, inverted to Y4 when enabled. |
| 7 | A5 | input | Data input A5, inverted to Y5 when enabled. |
| 8 | A6 | input | Data input A6, inverted to Y6 when enabled. |
| 9 | A7 | input | Data input A7, inverted to Y7 when enabled. |
| 10 | GND | power_in | Ground. |
| 11 | ~{Y7} | tri_state | Inverting 3-state output Y7, ±24mA drive. |
| 12 | ~{Y6} | tri_state | Inverting 3-state output Y6, ±24mA drive. |
| 13 | ~{Y5} | tri_state | Inverting 3-state output Y5, ±24mA drive. |
| 14 | ~{Y4} | tri_state | Inverting 3-state output Y4, ±24mA drive. |
| 15 | ~{Y3} | tri_state | Inverting 3-state output Y3, ±24mA drive. |
| 16 | ~{Y2} | tri_state | Inverting 3-state output Y2, ±24mA drive. |
| 17 | ~{Y1} | tri_state | Inverting 3-state output Y1, ±24mA drive. |
| 18 | ~{Y0} | tri_state | Inverting 3-state output Y0, ±24mA drive. |
| 19 | ~{OE2} | input | Active-low output enable 2; outputs are high-impedance when OE1 or OE2 is high. |
