AiP74HC165SA16.TR from Wuxi I core Elec AiP74HC165SA16 TR, 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 PL=L, data on D0-D7 is loaded into the shift register regardless of CP.
2	CP	input	Clock input, low-to-high edge triggered. Shifts serial data through the register when CE is low and PL is high.
3	D4	input	Parallel data input bit 4 (Dn). Loaded into the corresponding shift-register stage when PL is low.
4	D5	input	Parallel data input bit 5 (Dn). Loaded into the corresponding shift-register stage when PL is low.
5	D6	input	Parallel data input bit 6 (Dn). Loaded into the corresponding shift-register stage when PL is low.
6	D7	input	Parallel data input bit 7 (Dn). Last stage that appears at Q7 after a parallel load.
7	/Q7	output	Complementary serial output of the last (Q7) stage. Inverse of the Q7 pin.
8	GND	power_in	Ground reference (0 V).
9	Q7	output	Serial output from the last (Q7) stage of the shift register.
10	DS	input	Serial data input. Shifted into stage Q0 on each CP rising edge while CE is low and PL is high.
11	D0	input	Parallel data input bit 0 (Dn). Loaded into the corresponding shift-register stage when PL is low.
12	D1	input	Parallel data input bit 1 (Dn). Loaded into the corresponding shift-register stage when PL is low.
13	D2	input	Parallel data input bit 2 (Dn). Loaded into the corresponding shift-register stage when PL is low.
14	D3	input	Parallel data input bit 3 (Dn). Loaded into the corresponding shift-register stage when PL is low.
15	CE	input	Clock enable input, active low. When CE is low the clock is enabled; a high on CE inhibits (gates off) the CP input.
16	VCC	power_in	Supply voltage. AiP74HC165: 2.0-6.0 V (5.0 V typ). AiP74HCT165: 4.5-5.5 V (5.0 V typ). Absolute max +7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`aip74hc165sa16-tr.step`	217 KB	You want the bare part, or you mark your own boards.
`aip74hc165sa16-tr-etched.step`	3.2 MB	You want the part with `AiP74HC165SA16.TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 816 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.
