CD4066BM

lingxingic · Analog Switches, Multiplexers · SOP-14

CD4066BM from lingxingic, in a SOP-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 1Y bidirectional Analog switch 1 terminal Y. Bilateral I/O of switch 1 (paired with 1Z). Signal range 0 V to VDD.
2 1Z bidirectional Analog switch 1 terminal Z. Bilateral I/O of switch 1 (paired with 1Y).
3 2Z bidirectional Analog switch 2 terminal Z. Bilateral I/O of switch 2 (paired with 2Y).
4 2Y bidirectional Analog switch 2 terminal Y. Bilateral I/O of switch 2 (paired with 2Z).
5 2E input Enable input for switch 2 (active HIGH). HIGH closes the switch; LOW opens it. VIH ≥ 3.5 V @ VDD=5 V; VIL ≤ 1.5 V @ VDD=5 V.
6 3E input Enable input for switch 3 (active HIGH). HIGH closes the switch; LOW opens it.
7 VSS power_in Ground reference (0 V). Negative supply / substrate return.
8 3Y bidirectional Analog switch 3 terminal Y. Bilateral I/O of switch 3 (paired with 3Z).
9 3Z bidirectional Analog switch 3 terminal Z. Bilateral I/O of switch 3 (paired with 3Y).
10 4Z bidirectional Analog switch 4 terminal Z. Bilateral I/O of switch 4 (paired with 4Y).
11 4Y bidirectional Analog switch 4 terminal Y. Bilateral I/O of switch 4 (paired with 4Z).
12 4E input Enable input for switch 4 (active HIGH). HIGH closes the switch; LOW opens it.
13 1E input Enable input for switch 1 (active HIGH). HIGH closes the switch; LOW opens it.
14 VDD power_in Positive supply voltage, 3 V to 9 V recommended (absolute max +12 V). Decouple to VSS with a local ceramic capacitor.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: CD4066BM
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOP-14 (KiCad packages3D, STEP)
  • 3D model files: cd4066bm-etched.step / cd4066bm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cd4066bm.step / cd4066bm.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
cd4066bm.step 195 KB You want the bare part, or you mark your own boards.
cd4066bm-etched.step 2.3 MB You want the part with CD4066BM already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 559 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: lingxingic datasheet (14 pp, sha256 c719e5f4a019aa91, 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).
