## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OA | output | Channel A push-pull motor output; typical saturation voltage is 0.19 V at 100 mA and 0.36 V at 180 mA (max 0.25 V and 0.45 V). |
| 2 | VCC | power_in | Positive supply pin; operating supply range is 2.2 V to 6.5 V (absolute maximum -0.3 V to +8.0 V), and it is printed twice in the pinout table with pin 3. |
| 3 | VCC | power_in | Positive supply pin, internally the same net as pin 2; operating supply range is 2.2 V to 6.5 V (absolute maximum -0.3 V to +8.0 V). |
| 4 | OB | output | Channel B push-pull motor output; typical saturation voltage is 0.19 V at 100 mA and 0.36 V at 180 mA (max 0.25 V and 0.45 V). |
| 5 | GND | power_in | Power ground pin; it is printed twice in the pinout table, with pin 8. |
| 6 | IA | input | Channel A logic input, TTL/CMOS compatible; input low is 0 to 0.25VCC, input high is 0.7VCC to VCC, and input voltage must not exceed VCC (absolute minimum -0.3 V). |
| 7 | IB | input | Channel B logic input, TTL/CMOS compatible; input low is 0 to 0.25VCC, input high is 0.7VCC to VCC, and input voltage must not exceed VCC (absolute minimum -0.3 V). |
| 8 | GND | power_in | Power ground pin, internally the same net as pin 5. |
