TC4427AEUA

Microchip Tech · Gate Drive ICs · MSOP-8

TC4427AEUA 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 No connection.
2 IN A input Driver A input, a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis; ground it if unused.
3 GND power_in Ground, return path for the bias current and the high-peak current that discharges the external load capacitance; tie to a ground plane or use a very short trace to the bias supply return.
4 IN B input Driver B input, a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis; ground it if unused.
5 OUT B output Driver B output, a low-impedance CMOS push-pull output with equal-strength pull-up and pull-down devices and 1.5A peak output current.
6 VDD power_in Supply input rated 4.5V to 18V with respect to ground, to be bypassed with local ceramic capacitors sized for the capacitive load.
7 OUT A output Driver A output, a low-impedance CMOS push-pull output with equal-strength pull-up and pull-down devices and 1.5A peak output current.
8 NC unconnected No connection.
