UCC27324DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	INA	input	Input to channel A driver. TTL/CMOS compatible logic input, independent of VDD supply voltage. Threshold approximately 2.2V typical with hysteresis.
2	GND	power_in	Ground return for the device. All signals referenced to this pin.
3	INB	input	Input to channel B driver. TTL/CMOS compatible logic input, independent of VDD supply voltage. Threshold approximately 2.2V typical with hysteresis.
4	OUTB	output	Output of channel B driver. 4-A peak source/sink capability, rail-to-rail swing from GND to VDD. Drives MOSFET gate directly.
5	OUTB	output	Output of channel B driver (second pin, paralleled internally with pin 4 for current sharing). 4-A peak source/sink capability.
6	VDD	power_in	Supply voltage. 4.5V to 15V operating range, absolute max 16V. Bypass with low-ESR ceramic capacitor close to pin.
7	OUTA	output	Output of channel A driver (second pin, paralleled internally with pin 8 for current sharing). 4-A peak source/sink capability.
8	OUTA	output	Output of channel A driver. 4-A peak source/sink capability, rail-to-rail swing from GND to VDD. Drives MOSFET gate directly.
