CD4040BM

HGSEMI · Counters / Dividers · SOP-16

CD4040BM from HGSEMI, 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 Q12 output Buffered counter output, stage 12 (divide-by-4096). CMOS output, VDD swing.
2 Q6 output Buffered counter output, stage 6 (divide-by-64). CMOS output.
3 Q5 output Buffered counter output, stage 5 (divide-by-32). CMOS output.
4 Q7 output Buffered counter output, stage 7 (divide-by-128). CMOS output.
5 Q4 output Buffered counter output, stage 4 (divide-by-16). CMOS output.
6 Q3 output Buffered counter output, stage 3 (divide-by-8). CMOS output.
7 Q2 output Buffered counter output, stage 2 (divide-by-4). CMOS output.
8 VSS power_in Negative supply / ground reference (0 V).
9 Q1 output Buffered counter output, stage 1 (divide-by-2). CMOS output.
10 CLK input Clock input. Counter advances on the high-to-low (negative-going) transition of CLK. Schmitt-trigger CMOS input.
11 RST input Master reset. A high level asynchronously clears all 12 counter stages to zero; must be held low for normal counting.
12 Q9 output Buffered counter output, stage 9 (divide-by-512). CMOS output.
13 Q8 output Buffered counter output, stage 8 (divide-by-256). CMOS output.
14 Q10 output Buffered counter output, stage 10 (divide-by-1024). CMOS output.
15 Q11 output Buffered counter output, stage 11 (divide-by-2048). CMOS output.
16 VDD power_in Positive supply voltage. Operating range 3 V to 18 V (CD4000B series).

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: CD4040BM
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOP-16 (KiCad packages3D, STEP)
  • 3D model files: cd4040bm-etched.step / cd4040bm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cd4040bm.step / cd4040bm.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
cd4040bm.step 217 KB You want the bare part, or you mark your own boards.
cd4040bm-etched.step 2.2 MB You want the part with CD4040BM already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 564 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.

Provenance

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

  • Datasheet: HGSEMI datasheet (8 pp, sha256 44c6cde876d70aeb, 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).
