XL74HC165 from XINLUDA, in a SOP-16. 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	/PL	input	Asynchronous parallel load input (active LOW). When LOW, data on D0-D7 is loaded into the shift register asynchronously.
2	CP	input	Clock input, LOW-to-HIGH edge-triggered. Shifts serial data on rising edges when /CE is LOW and /PL is HIGH.
3	D4	input	Parallel data input bit 4. Loaded into the shift register on /PL LOW.
4	D5	input	Parallel data input bit 5. Loaded into the shift register on /PL LOW.
5	D6	input	Parallel data input bit 6. Loaded into the shift register on /PL LOW.
6	D7	input	Parallel data input bit 7 (MSB, appears first at Q7). Loaded into the shift register on /PL LOW.
7	/Q7	output	Complementary serial output from the last stage (inverted Q7).
8	GND	power_in	Ground reference, 0 V.
9	Q7	output	Serial output from the last stage of the shift register.
10	DS	input	Serial data input. Data entering the register serially on each LOW-to-HIGH CP transition when /PL is HIGH and /CE is LOW.
11	D0	input	Parallel data input bit 0. Loaded into the shift register on /PL LOW.
12	D1	input	Parallel data input bit 1. Loaded into the shift register on /PL LOW.
13	D2	input	Parallel data input bit 2. Loaded into the shift register on /PL LOW.
14	D3	input	Parallel data input bit 3. Loaded into the shift register on /PL LOW.
15	/CE	input	Clock enable input (active LOW). When LOW, CP is enabled; when HIGH, the CP input is disabled (hold).
16	VCC	power_in	Positive supply voltage, 2.0 V to 6.0 V (recommended).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`xl74hc165.step`	217 KB	You want the bare part, or you mark your own boards.
`xl74hc165-etched.step`	2.0 MB	You want the part with `XL74HC165` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 518 faces against 267 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
