Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | input | Driver 1 input; accepts logic signals with recommended levels 0.8V to 2.0V. |
| 2 | 1Y | tri_state | Driver 1 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 3 | 1Z | tri_state | Driver 1 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 4 | G | input | Active high enable input for Drivers 1 and 2; enables outputs when VIH ≥ 2.0V. |
| 5 | 2Z | tri_state | Driver 2 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 6 | 2Y | tri_state | Driver 2 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 7 | 2A | input | Driver 2 input; accepts logic signals with recommended levels 0.8V to 2.0V. |
| 8 | GND | power_in | Ground pin; network ground terminal for voltage reference. |
| 9 | 3A | input | Driver 3 input; accepts logic signals with recommended levels 0.8V to 2.0V. |
| 10 | 3Y | tri_state | Driver 3 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 11 | 3Z | tri_state | Driver 3 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 12 | G | input | Active low enable input for Drivers 3 and 4; enables outputs when VIL ≤ 0.8V. |
| 13 | 4Z | tri_state | Driver 4 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 14 | 4Y | tri_state | Driver 4 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C. |
| 15 | 4A | input | Driver 4 input; accepts logic signals with recommended levels 0.8V to 2.0V. |
| 16 | VCC | power_in | Power pin; supply voltage range 4.5V to 5.5V for single 5V supply operation. |
