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 | 2Y0 | bidirectional | Channel 0 independent input/output of switch bank 2. Connected to common 2Z when E=LOW and S2=LOW, S1=LOW. Analog signal path; RON typ 80 Ω at VDD-VEE = 10 V. |+| 2 | 2Y2 | bidirectional | Channel 2 independent input/output of switch bank 2. Connected to common 2Z when E=LOW and S2=HIGH, S1=LOW. Bidirectional analog signal path. |+| 3 | 2Z | bidirectional | Common output/input of switch bank 2. Routed to one of 2Y0..2Y3 as selected by S1/S2 when the E enable is LOW. Bidirectional analog signal. |+| 4 | 2Y3 | bidirectional | Channel 3 independent input/output of switch bank 2. Connected to common 2Z when E=LOW and S2=HIGH, S1=HIGH. Bidirectional analog signal path. |+| 5 | 2Y1 | bidirectional | Channel 1 independent input/output of switch bank 2. Connected to common 2Z when E=LOW and S2=LOW, S1=HIGH. Bidirectional analog signal path. |+| 6 | E | input | Active-LOW enable input (shown with overline on the datasheet). When LOW, the selected channel per S1/S2 is connected between nZ and the corresponding nYn. When HIGH, all switches are OFF (high impedance). Digital CMOS logic input. |+| 7 | VEE | power_in | Negative analog supply / substrate reference for the transmission gates. Referenced to VDD; range -18 V to +0.5 V (relative to VDD). Often tied to VSS for single-supply operation. |+| 8 | VSS | power_in | Digital ground / reference (0 V). All voltages in the datasheet referenced to VSS. |+| 9 | S2 | input | Digital select input, MSB of the 2-bit channel selector shared by both switch banks. Together with S1 selects one of nY0..nY3 to route to nZ when E is LOW. |+| 10 | S1 | input | Digital select input, LSB of the 2-bit channel selector shared by both switch banks. Together with S2 selects one of nY0..nY3 to route to nZ when E is LOW. |+| 11 | 1Y3 | bidirectional | Channel 3 independent input/output of switch bank 1. Connected to common 1Z when E=LOW and S2=HIGH, S1=HIGH. Bidirectional analog signal path. |+| 12 | 1Y0 | bidirectional | Channel 0 independent input/output of switch bank 1. Connected to common 1Z when E=LOW and S2=LOW, S1=LOW. Bidirectional analog signal path. |+| 13 | 1Z | bidirectional | Common output/input of switch bank 1. Routed to one of 1Y0..1Y3 as selected by S1/S2 when the E enable is LOW. Bidirectional analog signal. |+| 14 | 1Y1 | bidirectional | Channel 1 independent input/output of switch bank 1. Connected to common 1Z when E=LOW and S2=LOW, S1=HIGH. Bidirectional analog signal path. |+| 15 | 1Y2 | bidirectional | Channel 2 independent input/output of switch bank 1. Connected to common 1Z when E=LOW and S2=HIGH, S1=LOW. Bidirectional analog signal path. |+| 16 | VDD | power_in | Positive supply voltage. Operating range 3 V to 15 V; absolute max -0.5 V to +18 V referenced to VSS. Also sets the digital input logic thresholds (VIH ≥ 3.5 V at VDD=5 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `HEF4052BTT-Q100`+- `HEF4052BT-Q100`++## CAD (KiCad official)++- Symbol: `HEF4052BTT-Q100`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588908667671859200) (18 pp, sha256 `cc7ebf99a968f0c6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
