RS164XQ

Jiangsu RUNIC Tech · Shifting Register · TSSOP-14

RS164XQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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 A input Serial data input A. Gated with input B (logical AND) before entering the shift register; either input can serve as an active-high enable for the other.
2 B input Serial data input B. Gated with input A before entering the shift register; either input can serve as an active-high enable for the other.
3 Q0 output Parallel data output bit 0 (first stage of the shift register).
4 Q1 output Parallel data output bit 1.
5 Q2 output Parallel data output bit 2.
6 Q3 output Parallel data output bit 3.
7 GND power_in Ground reference (0 V).
8 CLK input Clock input. Data is shifted on the low-to-high (rising) edge transition.
9 CLR input Asynchronous master reset, active low. When low, all outputs are forced low independently of the other inputs.
10 Q4 output Parallel data output bit 4.
11 Q5 output Parallel data output bit 5.
12 Q6 output Parallel data output bit 6.
13 Q7 output Parallel data output bit 7 (last stage of the shift register).
14 VCC power_in Supply voltage input, 1.65 V to 5.5 V.

Two STEP files. Same geometry, different body top:

File Size Use it when
rs164xq.step 194 KB You want the bare part, or you mark your own boards.
rs164xq-etched.step 2.0 MB You want the part with RS164XQ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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: Jiangsu RUNIC Tech datasheet (15 pp, sha256 98f6ac3b85d1908e, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
