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 | Logic control input for switch 1 (SW1). CMOS/TTL compatible; VIL guaranteed ≤0.8 V, VIH guaranteed ≥2 V (from +5 V or ±5 V supplies; 1.4 V from +3 V supply). Logic 1 = SW1 ON (normally open switch). |+| 2 | D1 | passive | Drain terminal of analog switch 1. Bidirectional analog I/O; VD signal range clamped to V- − 0.3 V to V+ + 0.3 V. RDS(on) ≈ 72 Ω typ. at ±5 V supplies. |+| 3 | S1 | passive | Source terminal of analog switch 1. Bidirectional analog I/O; rail-to-rail signal handling within V- to V+ supplies. Continuous current 30 mA max. |+| 4 | V- | power_in | Negative analog supply. GND − 18 V max; V+ to V- ≤ 18 V. Tie to 0 V for single-supply operation or to a negative rail (typ. −5 V) for dual-supply operation. |+| 5 | GND | power_in | Digital/logic ground reference for the control inputs. Referenced separately from V-; GND to V- ≤ 18 V. |+| 6 | S4 | passive | Source terminal of analog switch 4. Bidirectional analog I/O; rail-to-rail signal handling within V- to V+ supplies. |+| 7 | D4 | passive | Drain terminal of analog switch 4. Bidirectional analog I/O. |+| 8 | IN4 | input | Logic control input for switch 4 (SW4). Logic 1 = SW4 ON (normally open). Input current ≤ 0.1 µA typ. |+| 9 | IN3 | input | Logic control input for switch 3 (SW3). Logic 1 = SW3 ON (normally open). |+| 10 | D3 | passive | Drain terminal of analog switch 3. Bidirectional analog I/O. |+| 11 | S3 | passive | Source terminal of analog switch 3. Bidirectional analog I/O. |+| 12 | NC | unconnected | No internal connection. Leave open or tie to a convenient potential; carries no signal. |+| 13 | V+ | power_in | Positive analog supply. 3 V to 16 V single-supply range, or +3 V to +8 V for dual-supply operation. V+ to V- ≤ 18 V absolute max. |+| 14 | S2 | passive | Source terminal of analog switch 2. Bidirectional analog I/O. |+| 15 | D2 | passive | Drain terminal of analog switch 2. Bidirectional analog I/O. |+| 16 | IN2 | input | Logic control input for switch 2 (SW2).
