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 | STR | input | Strobe input. When HIGH, data in the 8-bit shift register is transferred into the 8-bit storage register that drives the QP0-QP7 parallel outputs. |+| 2 | D | input | Serial data input. Sampled on the LOW-to-HIGH transition of CP and shifted into the first stage of the shift register. |+| 3 | CP | input | Clock input for the 8-stage shift register. Data on D is shifted on the LOW-to-HIGH (positive) transition of CP. |+| 4 | QP0 | tri_state | Parallel output bit 0 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 5 | QP1 | tri_state | Parallel output bit 1 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 6 | QP2 | tri_state | Parallel output bit 2 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 7 | QP3 | tri_state | Parallel output bit 3 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 8 | VSS | power_in | Ground supply voltage (0 V reference). All input/output voltages are referenced to VSS. |+| 9 | QS1 | output | Serial output for cascading. Data appears at QS1 on the LOW-to-HIGH transition of CP (allows cascading when clock edges are fast). |+| 10 | QS2 | output | Serial output for cascading. Data appears at QS2 on the next HIGH-to-LOW transition of CP (allows cascading when clock edges are slow). |+| 11 | QP7 | tri_state | Parallel output bit 7 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 12 | QP6 | tri_state | Parallel output bit 6 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 13 | QP5 | tri_state | Parallel output bit 5 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 14 | QP4 | tri_state | Parallel output bit 4 from the storage register. 3-state: driven when OE is HIGH, high-impedance when OE is LOW. |+| 15 | OE | input | Output enable input. HIGH enables the QP0-QP7 parallel outputs; LOW places them in a high-impedance OFF-state. Does not affect the state of the shift or storage registers. |+| 16 | VDD | power_in | Positive supply voltage. Recommended operating range 3 V to 15 V; absolute max 18 V referenced to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `HEF4094BTT`+- `HEF4094BTTT`++## CAD (KiCad official)++- Symbol: `HEF4094BT`+- 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/HEF4094BT.pdf) (15 pp, sha256 `0020655a9e8cad90`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
