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. |
