| 11 | Y8 | tri_state | Tri-state buffered output for channel 8; high-impedance when OE1 or OE2 is high |
| 12 | Y7 | tri_state | Tri-state buffered output for channel 7; high-impedance when OE1 or OE2 is high |
| 13 | Y6 | tri_state | Tri-state buffered output for channel 6; high-impedance when OE1 or OE2 is high |
| 14 | Y5 | tri_state | Tri-state buffered output for channel 5; high-impedance when OE1 or OE2 is high |
| 15 | Y4 | tri_state | Tri-state buffered output for channel 4; high-impedance when OE1 or OE2 is high |
| 16 | Y3 | tri_state | Tri-state buffered output for channel 3; high-impedance when OE1 or OE2 is high |
| 17 | Y2 | tri_state | Tri-state buffered output for channel 2; high-impedance when OE1 or OE2 is high |
| 18 | Y1 | tri_state | Tri-state buffered output for channel 1; high-impedance when OE1 or OE2 is high |
| 19 | OE2 | input | Active-low output enable control input; when high, all outputs enter high-impedance state |
| 20 | VCC | power_in | Supply voltage; recommended operating range 2.7 V to 3.6 V |
