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 | MR | input | Asynchronous master reset input, active LOW. Driving MR LOW forces all four Q outputs LOW and all Q-bar outputs HIGH independently of the clock. |+| 2 | Q0 | output | True (non-inverting) flip-flop output for channel 0. Reflects the stored D0 value after a LOW-to-HIGH CP edge. |+| 3 | Q0_N | output | Complementary (inverted) flip-flop output for channel 0. |+| 4 | D0 | input | Data input for flip-flop 0. Sampled on the LOW-to-HIGH transition of CP subject to setup/hold timing. |+| 5 | D1 | input | Data input for flip-flop 1. Sampled on the LOW-to-HIGH transition of CP. |+| 6 | Q1_N | output | Complementary (inverted) flip-flop output for channel 1. |+| 7 | Q1 | output | True (non-inverting) flip-flop output for channel 1. |+| 8 | GND | power_in | Ground reference (0 V). |+| 9 | CP | input | Common clock input, positive-edge triggered. All four flip-flops latch their D inputs on the LOW-to-HIGH transition. |+| 10 | Q2 | output | True (non-inverting) flip-flop output for channel 2. |+| 11 | Q2_N | output | Complementary (inverted) flip-flop output for channel 2. |+| 12 | D2 | input | Data input for flip-flop 2. Sampled on the LOW-to-HIGH transition of CP. |+| 13 | D3 | input | Data input for flip-flop 3. Sampled on the LOW-to-HIGH transition of CP. |+| 14 | Q3_N | output | Complementary (inverted) flip-flop output for channel 3. |+| 15 | Q3 | output | True (non-inverting) flip-flop output for channel 3. |+| 16 | VCC | power_in | Positive supply voltage. 2.0 V to 6.0 V for 74HC175; 4.5 V to 5.5 V for 74HCT175. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `74HC175DD`+- `74HC175DPW`++## CAD (KiCad official)++- Symbol: `74HC175D`+- 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/74HC175D.pdf) (16 pp, sha256 `374969b89f1ce8c5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
