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 | Y-side analog channel 0. Bidirectional analog switch terminal; connects to COMY when A=0,B=0 and INH=0. On-resistance ~60 Ω typ @ VDD-VSS=15 V. |+| 2 | Y2 | bidirectional | Y-side analog channel 2. Connects to COMY when A=0,B=1 and INH=0. |+| 3 | COMY | bidirectional | Y common terminal (Y OUT/IN). Shared node for the Y-side 4:1 mux; routes to Y0..Y3 based on A/B when INH=0. |+| 4 | Y3 | bidirectional | Y-side analog channel 3. Connects to COMY when A=1,B=1 and INH=0. |+| 5 | Y1 | bidirectional | Y-side analog channel 1. Connects to COMY when A=1,B=0 and INH=0. |+| 6 | INH | input | Inhibit / enable control input. When INH=high (VDD) all channels are OFF (high-Z); when INH=low, the A/B address selects one active channel per side. Digital logic level referenced to VSS. |+| 7 | VEE | power_in | Analog negative supply for the switch. Sets the lower rail of the analog signal range; VDD-VEE ≤ 15 V. Tie to VSS for unipolar analog signals. |+| 8 | VSS | power_in | Digital/logic ground and the reference for A, B, INH logic levels. |+| 9 | B | input | Binary address input B (bit 1) selecting which of the 4 X and Y channels is ON when INH=low. VIH ≥ 11 V typ @ VDD=15 V; VIL ≤ 4 V. |+| 10 | A | input | Binary address input A (bit 0) selecting which of the 4 X and Y channels is ON when INH=low. |+| 11 | X3 | bidirectional | X-side analog channel 3. Connects to COMX when A=1,B=1 and INH=0. |+| 12 | X0 | bidirectional | X-side analog channel 0. Connects to COMX when A=0,B=0 and INH=0. |+| 13 | COMX | bidirectional | X common terminal (X OUT/IN). Shared node for the X-side 4:1 mux; routes to X0..X3 based on A/B when INH=0. |+| 14 | X1 | bidirectional | X-side analog channel 1. Connects to COMX when A=1,B=0 and INH=0. |+| 15 | X2 | bidirectional | X-side analog channel 2. Connects to COMX when A=0,B=1 and INH=0. |+| 16 | VDD | power_in | Positive supply. VDD-VSS operating range 3-15 V (18 V absolute max). Bypass with 0.1 µF to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `CD4052BMBM/TR`+- `CD4052BMBE`+- `CD4052BMBN`+- `CD4052BMBMT/TR`+- `CD4052BMBMS/TR`+- `CD4052BMBLQ/TR`++## CAD (KiCad official)++- Symbol: `CD4052BM`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/cd4052bm-datasheet.pdf) (11 pp, sha256 `1ca4ab36c8479262`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
