TC4427EUA713

Microchip Tech · Gate Drive ICs · MSOP-8

TC4427EUA713 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 the driver is unused.
3 GND power_in Ground return pin, which should have a low-impedance connection to the bias supply return because high peak current flows out of it when the capacitive load is discharged.
4 IN B input Driver B input, a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis; ground it if the driver is unused.
5 OUT B output Driver B output, a low-impedance CMOS push-pull output with equal-strength pull-up and pull-down devices (non-inverting on TC4427).
6 VDD power_in Bias supply input rated 4.5V to 18V with respect to GND, to be bypassed with local ceramic capacitors (1.0 µF suggested).
7 OUT A output Driver A output, a low-impedance CMOS push-pull output with equal-strength pull-up and pull-down devices (non-inverting on TC4427).
8 NC unconnected No connection.
