TC4420EOA 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, the bias supply for the driver, rated 4.5V to 18V with respect to the ground pins and to be bypassed with a local ceramic capacitor of at least 1.0 µF. |
| 2 | INPUT | input | High-impedance TTL/CMOS compatible control input of the non-inverting TC4420, which can be driven from -5V up to VDD + 0.3V without damage. |
| 3 | NC | unconnected | No connection. |
| 4 | GND | power_in | Ground return path for the bias current and the high peak discharge currents of the load capacitor, 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 the high peak discharge currents of the load capacitor, to be tied to a ground plane or kept on very short traces; duplicate of pin 4 and must also be connected. |
| 6 | OUTPUT | output | CMOS push-pull output capable of driving a capacitive load with 6.0A peak current and withstanding 1.5A peak reverse current of either polarity. |
| 7 | OUTPUT | output | CMOS push-pull output capable of driving a capacitive load with 6.0A peak current and withstanding 1.5A peak reverse current of either polarity; duplicate of pin 6 and must also be connected. |
| 8 | VDD | power_in | Supply input, the bias supply for the driver, rated 4.5V to 18V with respect to the ground pins; duplicate of pin 1 and must also be connected. |
