## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | input | Driver 1 input, one of the four differential line driver inputs. |
| 2 | 1Y | output | Driver 1 output, the non-inverted leg of the differential pair. |
| 3 | 1Z | output | Driver 1 inverted output, the complementary leg of the differential pair. |
| 4 | G | input | Active-high enable input for the drivers, per the pin function table. |
| 5 | 2Z | output | Driver 2 inverted output, the complementary leg of the differential pair. |
| 6 | 2Y | output | Driver 2 output, the non-inverted leg of the differential pair. |
| 7 | 2A | input | Driver 2 input, one of the four differential line driver inputs. |
| 8 | GND | power_in | Ground pin; all voltages except differential voltages are referenced to this network ground terminal. |
| 9 | 3A | input | Driver 3 input, one of the four differential line driver inputs. |
| 10 | 3Y | output | Driver 3 output, the non-inverted leg of the differential pair. |
| 11 | 3Z | output | Driver 3 inverted output, the complementary leg of the differential pair. |
| 12 | G | input | Active-low enable input for the drivers, per the pin function table. |
| 13 | 4Z | output | Driver 4 inverted output, the complementary leg of the differential pair. |
| 14 | 4Y | output | Driver 4 output, the non-inverted leg of the differential pair. |
| 15 | 4A | input | Driver 4 input, one of the four differential line driver inputs. |
| 16 | VCC | power_in | Supply pin; recommended supply is 4.5 V to 5.5 V (5 V nominal). |
