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 | Y0 | bidirectional | Analog switch I/O for Y-bank channel 0. Selected to common Y when A=0, B=0 and INH=0. Signal must be between VEE and VDD; typical Ron ~120 Ω at VDD-VEE=10 V. |+| 2 | Y2 | bidirectional | Analog switch I/O for Y-bank channel 2. Selected to common Y when A=0, B=1 and INH=0. |+| 3 | Y | bidirectional | Common analog I/O for the Y switch bank (DP4T Y-common). Connects to Y0..Y3 based on A/B select and INH state. |+| 4 | Y3 | bidirectional | Analog switch I/O for Y-bank channel 3. Selected to common Y when A=1, B=1 and INH=0. |+| 5 | Y1 | bidirectional | Analog switch I/O for Y-bank channel 1. Selected to common Y when A=1, B=0 and INH=0. |+| 6 | INH | input | Inhibit (enable) control input, referenced to VSS. When INH=1 all switches are OFF (high impedance); when INH=0 the A/B select determines which channel is active. VIH ≥ 3.5 V, VIL ≤ 1.5 V at VDD=5 V. |+| 7 | VEE | power_in | Negative analog supply. Sets the lower limit of the analog switch signal range. Must satisfy VEE ≤ VSS; absolute maximum VDD − VEE = 18 V (recommended 15 V). |+| 8 | VSS | power_in | Digital/control ground reference. Control inputs (A, B, INH) are referenced to VSS. Typically tied to 0 V. |+| 9 | B | input | Digital select input B (MSB of the 2-bit channel address), referenced to VSS. Combined with A to pick one of four channels per bank when INH=0. |+| 10 | A | input | Digital select input A (LSB of the 2-bit channel address), referenced to VSS. Combined with B to pick one of four channels per bank when INH=0. |+| 11 | X3 | bidirectional | Analog switch I/O for X-bank channel 3. Selected to common X when A=1, B=1 and INH=0. |+| 12 | X0 | bidirectional | Analog switch I/O for X-bank channel 0. Selected to common X when A=0, B=0 and INH=0. |+| 13 | X | bidirectional | Common analog I/O for the X switch bank (DP4T X-common). Connects to X0..X3 based on A/B select and INH state. |+| 14 | X1 | bidirectional | Analog switch I/O for X-bank channel 1. Selected to common X when A=1, B=0 and INH=0. |+| 15 | X2 | bidirectional | Analog switch I/O for X-bank channel 2. Selected to common X when A=0, B=1 and INH=0. |+| 16 | VDD | power_in | Positive supply and control-input logic-high reference. Recommended 3.0 to 18 V relative to VEE; absolute maximum VDD − VEE = 18 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `MC14052BDR2GMC14052BDG`+- `MC14052BDR2G`+- `MC14052BDR2GNLV14052BDG`+- `MC14052BDR2GNLV14052BDR2G`+- `MC14052BDR2GMC14052BDTR2G`+- `MC14052BDR2GNLV14052BDTR2G`++## CAD (KiCad official)++- Symbol: `MC14052BDR2G`+- 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:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc14052b-d.pdf) (11 pp, sha256 `b980ba9c7a734408`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
