MIC4427YMM from Microchip Tech, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | Not internally connected. |
| 2 | INA | input | Control Input A is a TTL/CMOS compatible logic input that drives output A, with an input current of 1µA maximum between 0 and VS. |
| 3 | GND | power_in | Ground reference for the driver; the datasheet notes that individual ground returns or a ground plane are recommended for optimum switching speed. |
| 4 | INB | input | Control Input B is a TTL/CMOS compatible logic input that drives output B, with an input current of 1µA maximum between 0 and VS. |
| 5 | OUTB | output | Output B is a CMOS totem-pole output that swings within 25mV of the positive supply or ground. |
| 6 | VS | power_in | Supply input rated +4.5V to +18V. |
| 7 | OUTA | output | Output A is a CMOS totem-pole output that swings within 25mV of the positive supply or ground. |
| 8 | NC | unconnected | Not internally connected. |
