| 11 | 3Z | tri_state | Driver 3 inverted three-state output; VOH 2.4-3.4V, VOL 0.2-0.4V. |
| 12 | G | input | Active-low enable input; enables drivers when low, places outputs in high-impedance when high. |
| 13 | 4Z | tri_state | Driver 4 inverted three-state output; VOH 2.4-3.4V, VOL 0.2-0.4V. |
| 14 | 4Y | tri_state | Driver 4 three-state output; VOH 2.4-3.4V, VOL 0.2-0.4V. |
| 15 | 4A | input | Driver 4 input; TTL/CMOS logic input threshold VIH=2V, VIL=0.8V. |
| 16 | VCC | power_out | Power supply; +5V nominal (4.5-5.5V operating range). |
