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 | A0 | input | Address bit 0 (LSB) of the 3-bit channel-select bus. TTL-compatible: VIL ≤ 0.8 V, VIH ≥ 2.4 V. |+| 2 | EN | input | Active-high enable. EN = 0 turns all switches OFF; EN = 1 enables the channel selected by A0/A1/A2. TTL-compatible. |+| 3 | V- | power_in | Negative analog supply. Dual-supply range ±5 V to ±20 V, or tie to GND for single-supply +5 V to +36 V operation. V+ to V- ≤ 44 V absolute max. |+| 4 | S1 | passive | Analog switch source input, channel 1. Selected when A2A1A0 = 000 and EN = 1. Signal range V- to V+. |+| 5 | S2 | passive | Analog switch source input, channel 2. Selected when A2A1A0 = 001 and EN = 1. |+| 6 | S3 | passive | Analog switch source input, channel 3. Selected when A2A1A0 = 010 and EN = 1. |+| 7 | S4 | passive | Analog switch source input, channel 4. Selected when A2A1A0 = 011 and EN = 1. |+| 8 | D | passive | Common analog drain (multiplexer output). Bidirectional; conducts equally in both directions. RDS(on) ≈ 100 Ω, peak pulsed current 100 mA (1 ms, 10 % duty). |+| 9 | S8 | passive | Analog switch source input, channel 8. Selected when A2A1A0 = 111 and EN = 1. |+| 10 | S7 | passive | Analog switch source input, channel 7. Selected when A2A1A0 = 110 and EN = 1. |+| 11 | S6 | passive | Analog switch source input, channel 6. Selected when A2A1A0 = 101 and EN = 1. |+| 12 | S5 | passive | Analog switch source input, channel 5. Selected when A2A1A0 = 100 and EN = 1. |+| 13 | V+ | power_in | Positive analog supply. Dual-supply ±5 V to ±20 V, or single-supply +5 V to +36 V referenced to GND (V- tied to GND). Typical I+ = 10 µA. |+| 14 | GND | power_in | Digital/logic ground reference. GND-to-V- absolute max -25 V. |+| 15 | A2 | input | Address bit 2 (MSB) of the 3-bit channel-select bus. TTL-compatible. |+| 16 | A1 | input | Address bit 1 of the 3-bit channel-select bus. TTL-compatible. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Vishay |+| Package | TSSOP-16 |+| Category | Comm/UART |+| Pins | 16 |++## Ordering variants++- `DG408DQ-T1-E3DQ-E3`+- `DG408DQ-T1-E3DQ-T1-E3`+- `DG408DQ-T1-E3DY`+- `DG408DQ-T1-E3DY-E3`+- `DG408DQ-T1-E3DY-T1`+- `DG408DQ-T1-E3DY-T1-E3`+- `DG408DQ-T1-E3DJ`+- `DG408DQ-T1-E3DJ-E3`++## CAD (KiCad official)++- Symbol: `DG408DQ-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/dg408dq-t1-e3-datasheet.pdf) (17 pp, sha256 `950673efec0223bf`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
