| PIN | NAME | FUNCTION | DESCRIPTION |
|---|---|---|---|
| 1 | VCCA | VCC1 | SYSTEM-1 supply voltage (0.65 V to 3.6V) |
| 2 | GND | GND | Device GND |
| 3 | A | OUT | Output level depends on VCC1 voltage. |
| 4 | B | IN | Input threshold value depends on VCC2 voltage. |
| 5 | DIR | DIR | GND (low level) determines B-port to A-port direction. |
| 6 | VCCB | VCC2 | SYSTEM-2 supply voltage (0.65 V to 3.6V) |
