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 for one clock period when the internal counter is in state 5. |+| 2 | Q1 | output | Decoded active-HIGH output 1. HIGH for one clock period when the counter is in state 1. |+| 3 | Q0 | output | Decoded active-HIGH output 0. HIGH for one clock period when the counter is in state 0 (also the state after master reset). |+| 4 | Q2 | output | Decoded active-HIGH output 2. |+| 5 | Q6 | output | Decoded active-HIGH output 6. |+| 6 | Q7 | output | Decoded active-HIGH output 7. |+| 7 | Q3 | output | Decoded active-HIGH output 3. |+| 8 | VSS | power_in | Ground supply reference (0 V). |+| 9 | Q8 | output | Decoded active-HIGH output 8. |+| 10 | Q4 | output | Decoded active-HIGH output 4. |+| 11 | Q9 | output | Decoded active-HIGH output 9. HIGH during the 10th clock state before the counter rolls back to Q0. |+| 12 | Q5-9 | output | Carry-out: HIGH while the counter is in states 0..4 and LOW while in states 5..9, providing one output pulse per counter cycle to cascade counters. |+| 13 | CE | input | Clock enable (active LOW). When HIGH, the counter is inhibited and ignores clock edges; when LOW, the counter advances on rising CP edges. |+| 14 | CP | input | Clock input. The counter advances on the LOW-to-HIGH transition of CP while CE is LOW. |+| 15 | MR | input | Master reset (active HIGH, asynchronous). A HIGH level forces the counter to state 0 (Q0 HIGH) independent of CP and CE. |+| 16 | VDD | power_in | Positive supply voltage, 3 V to 15 V (absolute max 18 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `HEF4017BTT`+- `HEF4017BTP`+- `HEF4017BTTT`++## CAD (KiCad official)++- Symbol: `HEF4017BT`+- 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:** [Nexperia datasheet](https://assets.nexperia.com/documents/data-sheet/HEF4017BT.pdf) (18 pp, sha256 `cb1aa5b34d48ab0f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
