DG211BDQ-T1-E3 from Vishay, in a TSSOP-16. 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).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`dg211bdq-t1-e3.step`	205 KB	You want the bare part, or you mark your own boards.
`dg211bdq-t1-e3-etched.step`	2.7 MB	You want the part with `DG211BDQ-T1-E3` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 684 faces against 255 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
