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 | IN1 | input | Digital control input for switch 1. TTL/CMOS compatible; VINH ≥ 2.4 V (logic 1) opens the switch on DG211B, VINL ≤ 0.8 V (logic 0) closes it. Input current ±1 µA max, input capacitance ~5 pF. |+| 2 | D1 | passive | Drain terminal of analog switch 1. Bidirectional analog signal terminal; connects to source S1 when switch is ON. Signal range ±15 V typical (V+ = +15 V, V- = -15 V); RDS(on) ~45 Ω typ. |+| 3 | S1 | passive | Source terminal of analog switch 1. Bidirectional analog signal terminal paired with D1. Continuous current rating 30 mA; signals exceeding V+ or V- are clamped by internal diodes. |+| 4 | V- | power_in | Negative analog supply rail. Typical -15 V for dual-supply operation; supports down to -22 V absolute max. Sets the negative limit of the analog signal range. |+| 5 | GND | power_in | Ground reference for digital logic and single-supply operation. Referenced to V+ up to 25 V max. In single-supply mode V- is tied to GND. |+| 6 | S4 | passive | Source terminal of analog switch 4. Bidirectional analog signal terminal paired with D4. |+| 7 | D4 | passive | Drain terminal of analog switch 4. Bidirectional analog signal terminal; connects to S4 when switch is ON. |+| 8 | IN4 | input | Digital control input for switch 4. TTL/CMOS compatible logic-level input; controls D4-S4 channel per truth table (logic 1 opens on DG211B). |+| 9 | IN3 | input | Digital control input for switch 3. TTL/CMOS compatible; controls D3-S3 channel per truth table. |+| 10 | D3 | passive | Drain terminal of analog switch 3. Bidirectional analog signal terminal paired with S3. |+| 11 | S3 | passive | Source terminal of analog switch 3. Bidirectional analog signal terminal paired with D3. |+| 12 | VL | power_in | Logic supply rail for digital inputs. Typically +5 V; sets the reference level for the TTL/CMOS input thresholds (VINH ≥ 2.4 V, VINL ≤ 0.8 V). Logic supply current IL ~10 µA typical. |+| 13 | V+ | power_in | Positive analog supply rail. Typical +15 V for dual-supply operation; supports up to +22 V absolute max. Sets the positive limit of the analog signal range. |+| 14 | S2 | passive | Source terminal of analog switch 2. Bidirectional analog signal terminal paired with D2. |+| 15 | D2 | passive | Drain terminal of analog switch 2. Bidirectional analog signal terminal paired with S2. |+| 16 | IN2 | input | Digital control input for switch 2. TTL/CMOS compatible; controls D2-S2 channel per truth table. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Vishay |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `DG211BDY-T1-E3DY`+- `DG211BDY-T1-E3DY-T1`+- `DG211BDY-T1-E3DY-E3`+- `DG211BDY-T1-E3DY-T1-E3`+- `DG211BDY-T1-E3DJ`+- `DG211BDY-T1-E3DJ-E3`+- `DG211BDY-T1-E3DQ`+- `DG211BDY-T1-E3DQ-T1`+- `DG211BDY-T1-E3DQ-E3`+- `DG211BDY-T1-E3DQ-T1-E3`++## CAD (KiCad official)++- Symbol: `DG211BDY-T1-E3`+- 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:** [Vishay datasheet](docs/dg211bdy-t1-e3-datasheet.pdf) (14 pp, sha256 `d32f2a163665a3fd`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
