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 logic control input for switch 1. TTL/CMOS compatible: VINH ≥ 2.4 V (logic high), VINL ≤ 0.8 V (logic low). For DG211B, logic 0 = switch ON, logic 1 = switch OFF (normally closed). |+| 2 | D1 | passive | Drain terminal of analog switch 1. Bidirectional analog signal path to S1 when the switch is ON. RDS(on) ≈ 50 Ω typ; analog signal range ±15 V (±15 V supplies). Continuous current rating 30 mA. |+| 3 | S1 | passive | Source terminal of analog switch 1. Bidirectional analog signal path to D1 when the switch is ON. True bi-directional performance; blocks to supply rails in the off condition. |+| 4 | V- | power_in | Negative analog supply. Typically -15 V for dual-supply operation; may be tied to GND for single-supply operation (up to +25 V on V+). Absolute max V+ to V- = 44 V. |+| 5 | GND | power_in | Digital ground / reference for logic inputs. Absolute maximum voltage 25 V referenced to V-. |+| 6 | S4 | passive | Source terminal of analog switch 4. Bidirectional analog signal path to D4 when the switch is ON. |+| 7 | D4 | passive | Drain terminal of analog switch 4. Bidirectional analog signal path to S4 when the switch is ON. RDS(on) ≈ 50 Ω typ. |+| 8 | IN4 | input | Digital logic control input for switch 4. TTL/CMOS compatible. DG211B: logic 0 = ON, logic 1 = OFF (normally closed). |+| 9 | IN3 | input | Digital logic control input for switch 3. TTL/CMOS compatible. DG211B: logic 0 = ON, logic 1 = OFF (normally closed). |+| 10 | D3 | passive | Drain terminal of analog switch 3. Bidirectional analog signal path to S3 when the switch is ON. |+| 11 | S3 | passive | Source terminal of analog switch 3. Bidirectional analog signal path to D3 when the switch is ON. |+| 12 | VL | power_in | Logic supply. Typically +5 V; sets the logic threshold reference for the digital control inputs (TTL/CMOS compatible). |+| 13 | V+ | power_in | Positive analog supply. Typically +15 V for dual-supply operation; up to +25 V for single-supply operation. Sets positive analog signal range and clamp limits. |+| 14 | S2 | passive | Source terminal of analog switch 2. Bidirectional analog signal path to D2 when the switch is ON. |+| 15 | D2 | passive | Drain terminal of analog switch 2. Bidirectional analog signal path to S2 when the switch is ON. |+| 16 | IN2 | input | Digital logic control input for switch 2. TTL/CMOS compatible. DG211B: logic 0 = ON, logic 1 = OFF (normally closed). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Vishay |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `DG211BDQ-T1-E3`+- `DG211BDQ-T1-E3DQ-E3`+- `DG211BDQ-T1-E3DY`+- `DG211BDQ-T1-E3DY-T1`+- `DG211BDQ-T1-E3DY-E3`+- `DG211BDQ-T1-E3DY-T1-E3`+- `DG211BDQ-T1-E3DJ`+- `DG211BDQ-T1-E3DJ-E3`++## CAD (KiCad official)++- Symbol: `DG211BDQ-T1-E3`+- 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:** [Vishay datasheet](docs/dg211bdq-t1-e3-datasheet.pdf) (14 pp, sha256 `054b5a2872d31f77`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
