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 | Q5 | output | Decoded active-high output 5. High during the sixth clock state; typical CMOS output drive at VDD = 5-15 V. |+| 2 | Q1 | output | Decoded active-high output 1. High during the second clock state. |+| 3 | Q0 | output | Decoded active-high output 0. High during the first clock state and following reset. |+| 4 | Q2 | output | Decoded active-high output 2. High during the third clock state. |+| 5 | Q6 | output | Decoded active-high output 6. High during the seventh clock state. |+| 6 | Q7 | output | Decoded active-high output 7. High during the eighth clock state. |+| 7 | Q3 | output | Decoded active-high output 3. High during the fourth clock state. |+| 8 | VSS | power_in | Negative supply / ground return. Tie to 0 V. |+| 9 | Q8 | output | Decoded active-high output 8. High during the ninth clock state. |+| 10 | Q4 | output | Decoded active-high output 4. High during the fifth clock state. |+| 11 | Q9 | output | Decoded active-high output 9. High during the tenth clock state. |+| 12 | CARRY_OUT | output | Carry-out. Completes one full cycle every 10 clock input cycles; used to cascade CD4017 stages as a divide-by-10 chain. |+| 13 | CLOCK_INHIBIT | input | Clock inhibit / clock-enable. When high, the counter is inhibited and holds its current state; when low, the counter advances on the positive clock edge. |+| 14 | CLOCK | input | Clock input. The counter advances one count on each positive-going clock transition while CLOCK_INHIBIT and RESET are low. |+| 15 | RESET | input | Asynchronous reset (active high). Forces the counter to state 0 (Q0 high, all other outputs low) independent of the clock. |+| 16 | VDD | power_in | Positive supply. Operating range 3 V to 15 V (absolute max 18 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `CD4017CMCD4017BE`+- `CD4017CMCD4017BM`+- `CD4017CMCD4017BPW`++## CAD (KiCad official)++- Symbol: `CD4017CM`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/cd4017cm-datasheet.pdf) (16 pp, sha256 `141ca40d50613ba8`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
