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 | 2Y1 | bidirectional | Independent input or output of switch 2, channel Y1. Selected as the connected path to 2Z when S2 is HIGH (and E is LOW). |+| 2 | 2Y0 | bidirectional | Independent input or output of switch 2, channel Y0. Selected as the connected path to 2Z when S2 is LOW (and E is LOW). |+| 3 | 3Y1 | bidirectional | Independent input or output of switch 3, channel Y1. Selected as the connected path to 3Z when S3 is HIGH (and E is LOW). |+| 4 | 3Z | bidirectional | Common input or output of switch 3. Routes to 3Y0 or 3Y1 based on the S3 select input while E is LOW. |+| 5 | 3Y0 | bidirectional | Independent input or output of switch 3, channel Y0. Selected as the connected path to 3Z when S3 is LOW (and E is LOW). |+| 6 | E | input | Enable input, active LOW. When LOW, all three switches operate per their Sn select inputs; when HIGH, all switches are turned off (high-Z). |+| 7 | VEE | power_in | Negative analog supply voltage. Sets the lower rail of the analog switch (allows bipolar analog signals up to VCC-VEE = 10 V max). |+| 8 | GND | power_in | Ground / digital reference (VSS = 0 V). Reference for the digital control inputs (E, Sn). |+| 9 | S3 | input | Digital select input for switch 3. LOW selects 3Y0<->3Z; HIGH selects 3Y1<->3Z (when E is LOW). |+| 10 | S2 | input | Digital select input for switch 2. LOW selects 2Y0<->2Z; HIGH selects 2Y1<->2Z (when E is LOW). |+| 11 | S1 | input | Digital select input for switch 1. LOW selects 1Y0<->1Z; HIGH selects 1Y1<->1Z (when E is LOW). |+| 12 | 1Y0 | bidirectional | Independent input or output of switch 1, channel Y0. Selected as the connected path to 1Z when S1 is LOW (and E is LOW). |+| 13 | 1Y1 | bidirectional | Independent input or output of switch 1, channel Y1. Selected as the connected path to 1Z when S1 is HIGH (and E is LOW). |+| 14 | 1Z | bidirectional | Common input or output of switch 1. Routes to 1Y0 or 1Y1 based on the S1 select input while E is LOW. |+| 15 | 2Z | bidirectional | Common input or output of switch 2. Routes to 2Y0 or 2Y1 based on the S2 select input while E is LOW. |+| 16 | VCC | power_in | Positive supply voltage. 2.0-10.0 V for 74HC4053 (VCC-GND); 4.5-5.5 V for 74HCT4053. Also the upper rail of the analog switch. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `74HC4053DD`+- `74HC4053DPW`+- `74HC4053DBQ`+- `74HC4053DBZ`++## CAD (KiCad official)++- Symbol: `74HC4053D`+- 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/74HC4053D.pdf) (27 pp, sha256 `2dd05bcd3aafe141`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
