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 | VCC | power_in | Positive supply voltage. Recommended operating range 3 V to 18 V; absolute max 20 V referenced to VSS. |+| 2 | G | output | Non-inverting buffer output 1 (G = A). Drives up to 2 TTL loads; typical IOL ≥ 3.3 mA at VOL ≤ 0.4 V with VCC = 5 V. |+| 3 | A | input | Buffer input 1. High-impedance CMOS input; VIH may exceed VCC (up to 15 V regardless of VCC), enabling logic-level down-conversion. |+| 4 | H | output | Non-inverting buffer output 2 (H = B). |+| 5 | B | input | Buffer input 2. High-impedance CMOS input; VIH may exceed VCC. |+| 6 | I | output | Non-inverting buffer output 3 (I = C). |+| 7 | C | input | Buffer input 3. High-impedance CMOS input; VIH may exceed VCC. |+| 8 | VSS | power_in | Negative supply / ground reference (0 V in single-supply operation). |+| 9 | D | input | Buffer input 4. High-impedance CMOS input; VIH may exceed VCC. |+| 10 | J | output | Non-inverting buffer output 4 (J = D). |+| 11 | E | input | Buffer input 5. High-impedance CMOS input; VIH may exceed VCC. |+| 12 | K | output | Non-inverting buffer output 5 (K = E). |+| 13 | NC | unconnected | No internal connection. Leave floating or tie to VSS/VCC per board practice. |+| 14 | F | input | Buffer input 6. High-impedance CMOS input; VIH may exceed VCC. |+| 15 | L | output | Non-inverting buffer output 6 (L = F). |+| 16 | NC | unconnected | No internal connection. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `CD4050BDRD`+- `CD4050BDRDR`+- `CD4050BDRDW`+- `CD4050BDRDWR`+- `CD4050BDRE`+- `CD4050BDRNS`+- `CD4050BDRNSR`+- `CD4050BDRPW`+- `CD4050BDRPWR`++## CAD (KiCad official)++- Symbol: `CD4050BDR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/cd4050b.pdf) (39 pp, sha256 `ee56c7e624d98e37`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
