CMOS push-pull output, IO max ±25 mA. |+| 2 | Q12 | output | Buffered counter output; stage 12 (divide-by-4096). CMOS push-pull output. |+| 3 | Q13 | output | Buffered counter output; stage 13 (divide-by-8192). CMOS push-pull output. |+| 4 | Q5 | output | Buffered counter output; stage 5 (divide-by-32). CMOS push-pull output. |+| 5 | Q4 | output | Buffered counter output; stage 4 (divide-by-16). CMOS push-pull output. |+| 6 | Q6 | output | Buffered counter output; stage 6 (divide-by-64). CMOS push-pull output. |+| 7 | Q3 | output | Buffered counter output; stage 3 (divide-by-8). CMOS push-pull output. |+| 8 | GND | power_in | Ground reference (0 V). |+| 9 | CTC | passive | External capacitor connection for the on-chip RC/crystal oscillator. Leave floating if RS is driven by an external clock. |+| 10 | RTC | passive | External resistor connection for the on-chip RC/crystal oscillator. Leave floating if RS is driven by an external clock. |+| 11 | RS | input | Oscillator pin / external clock input. Counter advances on HIGH-to-LOW transitions of RS. |+| 12 | MR | input | Master reset input, active HIGH. A HIGH level clears all counter stages and forces all outputs LOW independent of other inputs. |+| 13 | Q8 | output | Buffered counter output; stage 8 (divide-by-256). CMOS push-pull output. |+| 14 | Q7 | output | Buffered counter output; stage 7 (divide-by-128). CMOS push-pull output. |+| 15 | Q9 | output | Buffered counter output; stage 9 (divide-by-512). CMOS push-pull output. |+| 16 | VCC | power_in | Positive supply voltage. 2.0 V to 6.0 V for 74HC4060; 4.5 V to 5.5 V for 74HCT4060. Absolute max +7 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `74HC4060DD`+- `74HC4060DPW`+- `74HC4060DBQ`++## CAD (KiCad official)++- Symbol: `74HC4060D`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-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/74HC4060D.pdf) (19 pp, sha256 `9d9d4fbd139e4a1e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
