TC4420CPA 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 VDD power_in Supply input, 4.5V to 18V with respect to ground; bypass with a local ceramic capacitor of at least 1.0 µF, and must be connected together with pin 8.
2 INPUT input High-impedance TTL/CMOS compatible control input that withstands -5V to VDD + 0.3V; avoid slow edges to prevent double-pulsing of the output.
3 NC unconnected No connection.
4 GND power_in Ground return for bias current and high peak load-discharge currents; must be connected together with pin 5, tied to a ground plane or very short traces.
5 GND power_in Ground return for bias current and high peak load-discharge currents; must be connected together with pin 4, tied to a ground plane or very short traces.
6 OUTPUT output CMOS push-pull output driving capacitive loads with 6.0A peak current and withstanding 1.5A reverse current; must be connected together with pin 7.
7 OUTPUT output CMOS push-pull output driving capacitive loads with 6.0A peak current and withstanding 1.5A reverse current; must be connected together with pin 6.
8 VDD power_in Supply input, 4.5V to 18V with respect to ground; must be connected together with pin 1.
