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 select bit 0 (LSB). TTL-compatible digital input; VIH ≥ 2.4 V, VIL ≤ 0.8 V. |+| 2 | EN | input | Active-high enable input. EN = 0 opens all switches; EN = 1 enables the channel selected by A0/A1/A2. TTL-compatible. |+| 3 | V- | power_in | Negative analog supply rail. Typically -15 V for ±15 V dual-supply operation, or 0 V (tied to GND) for single-supply operation. V+ to V- max 44 V. |+| 4 | S1 | passive | Analog switch source input for channel 1. Connected to D when address = 000 and EN = 1. Analog signal range V- to V+ (100 Ω typical RDS(on)). |+| 5 | S2 | passive | Analog switch source input for channel 2. Selected when address = 001 and EN = 1. |+| 6 | S3 | passive | Analog switch source input for channel 3. Selected when address = 010 and EN = 1. |+| 7 | S4 | passive | Analog switch source input for channel 4. Selected when address = 011 and EN = 1. |+| 8 | D | passive | Common drain (multiplexer output/input). Bidirectional analog node connected to the selected S1-S8 channel. Peak current 100 mA pulsed, 30 mA continuous per terminal. |+| 9 | S8 | passive | Analog switch source input for channel 8. Selected when address = 111 and EN = 1. |+| 10 | S7 | passive | Analog switch source input for channel 7. Selected when address = 110 and EN = 1. |+| 11 | S6 | passive | Analog switch source input for channel 6. Selected when address = 101 and EN = 1. |+| 12 | S5 | passive | Analog switch source input for channel 5. Selected when address = 100 and EN = 1. |+| 13 | V+ | power_in | Positive analog supply rail. Typically +15 V dual supply or +5 V to +36 V single supply. V+ to V- ≤ 44 V absolute maximum. |+| 14 | GND | power_in | Digital ground reference for logic inputs (A0, A1, A2, EN). GND to V- limited to -25 V. |+| 15 | A2 | input | Address select bit 2 (MSB). TTL-compatible digital input; VIH ≥ 2.4 V, VIL ≤ 0.8 V. |+| 16 | A1 | input | Address select bit 1. TTL-compatible digital input; VIH ≥ 2.4 V, VIL ≤ 0.8 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Vishay |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `DG408DY-T1-E3`+- `DG408DY-T1-E3DY-E3`+- `DG408DY-T1-E3DJ`+- `DG408DY-T1-E3DJ-E3`+- `DG408DY-T1-E3DQ-E3`+- `DG408DY-T1-E3DQ-T1-E3`++## CAD (KiCad official)++- Symbol: `DG408DY-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/dg408dy-t1-e3-datasheet.pdf) (19 pp, sha256 `165f92f53a5974ee`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
