E-L9826 from STMicroelectronics, in a SOIC-20-300mil. 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	Out 6	output	Low-side driver output 6 with continuous output voltage limited to -0.7 V to 45 V and inductive turn-off clamping typically 50 V.
2	Out 1	output	Low-side driver output 1, controllable by SPI or by parallel input NON1, with short-circuit current limitation and thermal shutdown.
3	NRes	input	Asynchronous active-low reset input with internal pull-down of 50 kOhm to 250 kOhm, which resets all registers and disables all outputs.
4	NCS	input	Active-low SPI chip select, with the device selected while low and the rising edge latching the shift register data to the outputs.
5	GND	power_in	Device ground.
6	GND	power_in	Device ground.
7	NON1	input	Active-low parallel control input for output 1, internally pulled up so that output 1 is off when the input is open.
8	SDO	tri_state	Serial diagnostic data output that is tri-stated when NCS is high, with propagation delay from CLK to valid data of 100 ns maximum.
9	Out 8	output	Low-side driver output 8 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
10	Out 3	output	Low-side driver output 3 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
11	Out 5	output	Low-side driver output 5 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
12	Out 2	output	Low-side driver output 2, controllable by SPI or by parallel input NON2, with short-circuit current limitation and thermal shutdown.
13	SDI	input	Serial data input receiving the 8-bit SPI command, sampled on each CLK falling edge.
14	CLK	input	Serial clock input with maximum frequency of 3 MHz at 50% duty cycle.
15	GND	power_in	Device ground.
16	GND	power_in	Device ground.
17	NON2	input	Active-low parallel control input for output 2, internally pulled up so that output 2 is off when the input is open.
18	VCC	power_in	Supply voltage, specified for operation from 4.5 V to 5.5 V with absolute maximum of 7 V.
19	Out 7	output	Low-side driver output 7 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
20	Out 4	output	Low-side driver output 4 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
