74HC164D

Shenzhen Fuman · Shifting Register · SOP-14

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.

CAD (KiCad official)

  • Symbol: 74HC164D
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOP-14 (KiCad packages3D, STEP)
  • 3D model files: 74hc164d-etched.step / 74hc164d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74hc164d.step / 74hc164d.glb are the bare package body.

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Shenzhen Fuman datasheet (7 pp, sha256 eb798fbe5be69ee3, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
