| 6 | A5 | input | Data input for buffer channel 5. |
| 7 | A6 | input | Data input for buffer channel 6. |
| 8 | A7 | input | Data input for buffer channel 7. |
| 9 | A8 | input | Data input for buffer channel 8. |
| 10 | GND | power_in | Ground reference (0V). |
| 11 | Y8 | tri_state | 3-state buffered output for channel 8; high-impedance when either OE input is high. |
| 12 | Y7 | tri_state | 3-state buffered output for channel 7; high-impedance when either OE input is high. |
| 13 | Y6 | tri_state | 3-state buffered output for channel 6; high-impedance when either OE input is high. |
| 14 | Y5 | tri_state | 3-state buffered output for channel 5; high-impedance when either OE input is high. |
| 15 | Y4 | tri_state | 3-state buffered output for channel 4; high-impedance when either OE input is high. |
| 16 | Y3 | tri_state | 3-state buffered output for channel 3; high-impedance when either OE input is high. |
| 17 | Y2 | tri_state | 3-state buffered output for channel 2; high-impedance when either OE input is high. |
| 18 | Y1 | tri_state | 3-state buffered output for channel 1; high-impedance when either OE input is high. |
| 19 | OE2 | input | Active-low output-enable input; all outputs are high-impedance when high. |
| 20 | VCC | power_in | Positive supply voltage; recommended operating range 4.5V to 5.5V. |
