MCP14A0454-E from Microchip Tech, in a MSOP-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	ENA	input	Enable for Driver A. Active-high, low-threshold logic input (VEH ~1.6V, VEL ~1.3V, 0.3V hysteresis). Internal pull-up (~1.5 MΩ) to VDD lets the pin float for normal operation; driving below VEL disables and forces OUTA low regardless of INA.
2	INA	input	Input for Driver A. High-impedance, low-threshold TTL/CMOS-compatible logic input with hysteresis (VIH ~1.6V, VIL ~1.3V). Input voltage range GND-0.3V to VDD+0.3V; drives OUTA (non-inverting for MCP14A0454).
3	GND	power_in	Device ground; common return for input and output stages. Must have a low-impedance connection to the bias supply source return since high peak currents flow through it while discharging the capacitive load.
4	INB	input	Input for Driver B. High-impedance, low-threshold TTL/CMOS-compatible logic input with hysteresis (VIH ~1.6V, VIL ~1.3V). Input voltage range GND-0.3V to VDD+0.3V; drives OUTB (non-inverting for MCP14A0454).
5	OUTB	output	Push-pull gate-drive output for channel B (non-inverting on MCP14A0454; follows INB). CMOS output sources/sinks up to 4.5A peak (VDD=18V) with ROH ~1.7Ω / ROL ~1.3Ω typical. Latch-up protected to 500 mA reverse current.
6	VDD	power_in	Bias supply input for the driver; 4.5V to 18V operating range (absolute max +20V). Must be decoupled to GND with a local low-ESR bypass capacitor to source the peak gate-drive currents delivered to the load.
7	OUTA	output	Push-pull gate-drive output for channel A (non-inverting on MCP14A0454; follows INA). CMOS output sources/sinks up to 4.5A peak (VDD=18V) with ROH ~1.7Ω / ROL ~1.3Ω typical. Latch-up protected to 500 mA reverse current.
8	ENB	input	Enable for Driver B. Active-high, low-threshold logic input (VEH ~1.6V, VEL ~1.3V, 0.3V hysteresis). Internal pull-up (~1.5 MΩ) to VDD lets the pin float for normal operation; driving below VEL disables and forces OUTB low regardless of INB.
