TC4427VOA 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 | NC | unconnected | No connection; this pin is not used on the 8-pin PDIP/MSOP/SOIC package. |
| 2 | IN A | input | MOSFET driver input A is a high-impedance TTL/CMOS compatible input with 300 mV hysteresis, with a logic-high minimum of 2.4 V and logic-low maximum of 0.8 V, and it withstands negative inputs down to GND - 5 V. |
| 3 | GND | power_in | Device return pin that should have a low-impedance connection to the bias supply source return, since high peak current flows out of this pin when the capacitive load is discharged. |
| 4 | IN B | input | MOSFET driver input B is a high-impedance TTL/CMOS compatible input with 300 mV hysteresis, with a logic-high minimum of 2.4 V and logic-low maximum of 0.8 V, and it withstands negative inputs down to GND - 5 V. |
| 5 | OUT B | output | MOSFET driver output B is a low-impedance CMOS push-pull output with pull-up and pull-down devices of equal strength, giving matched rise and fall times, and it rated for 1.5 A peak output current. |
| 6 | VDD | power_in | Bias supply input for the MOSFET driver, rated for 4.5 V to 18 V with respect to GND, and it should be bypassed with local ceramic capacitors (1.0 µF suggested). |
| 7 | OUT A | output | MOSFET driver output A is a low-impedance CMOS push-pull output with pull-up and pull-down devices of equal strength, giving matched rise and fall times, and it rated for 1.5 A peak output current. |
| 8 | NC | unconnected | No connection; this pin is not used on the 8-pin PDIP/MSOP/SOIC package. |
