TC4420COA from Microchip Tech, in a SOIC-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 | VDD | power_in | Supply input rated 4.5V to 18V with respect to the ground pins, to be bypassed with a local ceramic capacitor of at least 1.0 µF. |
| 2 | INPUT | input | TTL/CMOS compatible high-impedance control input that can be driven as high as VDD + 0.3V or as low as -5V without upset or damage. |
| 3 | NC | unconnected | No connection. |
| 4 | GND | power_in | Ground return path for the bias current and high peak discharge currents, to be tied to a ground plane or kept on very short traces. |
| 5 | GND | power_in | Ground return path for the bias current and high peak discharge currents, to be tied to a ground plane or kept on very short traces; duplicate ground pin that must be connected for proper operation. |
| 6 | OUTPUT | output | CMOS push-pull output capable of 6.0A peak source and sink current and withstanding 1.5A peak reverse current of either polarity; duplicate output pin that must be connected for proper operation. |
| 7 | OUTPUT | output | CMOS push-pull output capable of 6.0A peak source and sink current and withstanding 1.5A peak reverse current of either polarity; duplicate output pin that must be connected for proper operation. |
| 8 | VDD | power_in | Supply input rated 4.5V to 18V with respect to the ground pins, to be bypassed with a local ceramic capacitor of at least 1.0 µF. |
