MIC4420YN from Microchip Tech, in a PDIP-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 | VS | power_in | Supply input (4.5V to 18V operating); duplicate of pin 8 and must be externally connected to it. |
| 2 | IN | input | Control input, logic high from 2.4V to VS, withstands a swing down to -5V and up to VS + 0.3V. |
| 3 | NC | unconnected | Not connected. |
| 4 | GND | power_in | Ground; duplicate of pin 5 and must be externally connected to it. |
| 5 | GND | power_in | Ground; duplicate of pin 4 and must be externally connected to it. |
| 6 | OUT | output | Non-inverting driver output with 6A peak current; duplicate of pin 7 and must be externally connected to it. |
| 7 | OUT | output | Non-inverting driver output with 6A peak current; duplicate of pin 6 and must be externally connected to it. |
| 8 | VS | power_in | Supply input (4.5V to 18V operating); duplicate of pin 1 and must be externally connected to it. |
