DG441LEDY-T1-GE3 from Vishay Intertech, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	IN1	input	Logic control input for switch 1; logic 0 is 0.8 V and logic 1 is 2.4 V, TTL and CMOS compatible.
2	D1	passive	Drain terminal of switch 1; signals exceeding V+ or V- are clamped by internal diodes, so the current must be limited.
3	S1	passive	Source terminal of switch 1; the switch conducts equally well in both directions when on and blocks input voltages up to the supply levels when off.
4	V-	power_in	Negative supply pin; single supply operation uses V- = 0 V with V+ from 3 V to 16 V, and dual supply ±3 V to ±8 V is recommended, with V+ to V- rated -0.3 V to +18 V.
5	GND	power_in	Ground reference pin for the digital logic inputs; the absolute maximum ratings list a GND to V- rating of 18 V.
6	S4	passive	Source terminal of switch 4; the switch conducts equally well in both directions when on and blocks input voltages up to the supply levels when off.
7	D4	passive	Drain terminal of switch 4; signals exceeding V+ or V- are clamped by internal diodes, so the current must be limited.
8	IN4	input	Logic control input for switch 4; logic 0 is 0.8 V and logic 1 is 2.4 V, TTL and CMOS compatible.
9	IN3	input	Logic control input for switch 3; logic 0 is 0.8 V and logic 1 is 2.4 V, TTL and CMOS compatible.
10	D3	passive	Drain terminal of switch 3; signals exceeding V+ or V- are clamped by internal diodes, so the current must be limited.
11	S3	passive	Source terminal of switch 3; the switch conducts equally well in both directions when on and blocks input voltages up to the supply levels when off.
12	NC	unconnected	No connection; the datasheet states no function for this pin.
13	V+	power_in	Positive supply pin; single supply range 3 V to 16 V, with V+ to V- rated -0.3 V to +18 V.
14	S2	passive	Source terminal of switch 2; the switch conducts equally well in both directions when on and blocks input voltages up to the supply levels when off.
15	D2	passive	Drain terminal of switch 2; signals exceeding V+ or V- are clamped by internal diodes, so the current must be limited.
16	IN2	input	Logic control input for switch 2; logic 0 is 0.8 V and logic 1 is 2.4 V, TTL and CMOS compatible.
