## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Power supply for side 1, recommended 2.7 V to 5.5 V with respect to GND1. |
| 2 | GND1 | power_in | Ground connection for VCC1. |
| 3 | INA | input | Input, channel A. |
| 4 | INB | input | Input, channel B. |
| 5 | INC | input | Input, channel C. |
| 6 | IND | input | Input, channel D. |
| 7 | NC | unconnected | No connect; pin is floating with no internal connection. |
| 8 | GND1 | power_in | Ground connection for VCC1. |
| 9 | GND2 | power_in | Ground connection for VCC2. |
| 10 | EN | input | Output enable; all output pins are enabled when EN is high or disconnected and disabled when EN is low. |
