74HC164D from Shenzhen Fuman, in a SOP-14. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	A	input	Gated serial data input A. ANDed with input B to feed the first flip-flop; a low on either A or B inhibits new data entry and forces the first stage low on the next CLK rising edge.
2	B	input	Gated serial data input B. ANDed with input A; must be high to permit A to control the first flip-flop.
3	QA	output	Shift register stage 1 parallel output. Updated on the rising edge of CLK.
4	QB	output	Shift register stage 2 parallel output.
5	QC	output	Shift register stage 3 parallel output.
6	QD	output	Shift register stage 4 parallel output.
7	GND	power_in	Ground reference. 0 V return for VDD.
8	CLOCK	input	Shift clock input. Data at A/B is captured on the low-to-high transition of CLK; fmax up to ~25 MHz at VCC=4.5 V (74HC).
9	CLEAR	input	Asynchronous active-low master clear. When low, all Q outputs are forced low independent of CLK.
10	QE	output	Shift register stage 5 parallel output.
11	QF	output	Shift register stage 6 parallel output.
12	QG	output	Shift register stage 7 parallel output.
13	QH	output	Shift register stage 8 (final) parallel output. Typically used as the serial-out to cascade additional 74HC164 devices.
14	VDD	power_in	Positive supply voltage. Recommended 2 V to 6 V (nominal 5 V); absolute max 7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74hc164d.step`	195 KB	You want the bare part, or you mark your own boards.
`74hc164d-etched.step`	1.8 MB	You want the part with `74HC164D` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 467 faces against 237 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.
