EL7156CSZ from RENESAS, 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	VS+	power_in	Positive supply voltage; the EL7156 is designed for supplies from 5V to 15V (4.5V to 16.5V maximum), with VS+ to VS- rated 5V to 16.5V in the operating voltage range.
2	OE	input	Output enable, active low; when OE is low both output switches open and OUT goes three-state (floating) between VL and VH.
3	IN	input	Logic input that selects OUT = VH when IN is low and OUT = VL when IN is high (with OE high); VIH is at least 2.4V and VIL is at most 0.8V at VS+ = 15V, and inputs are compatible with 3V and 5V CMOS signals.
4	GND	power_in	Ground reference for the device; the VS- to GND range is -5V to 0V and VS+ to GND is 5V to 16.5V.
5	VS-	power_in	Negative supply voltage; VS+ to VS- must stay within 5V to 16.5V and VL to VS- within 0V to 16.5V per the operating voltage range.
6	VL	power_in	Lower output voltage that OUT is switched to when IN is high; VL must remain below VH, otherwise the output-stage body diode turns on.
7	OUT	output	Driver output that connects to VH or VL depending on IN; it sources and sinks 3.5A peak in linear resistive operation and 200mA continuous.
8	VH	power_in	High output voltage that OUT is switched to when IN is low; VH must remain above VL, and VH to VS+ is limited to 0V to 16.5V.
