DG2524DN-T1-GE4 from Vishay, in a TQFN-16-EP(3x3). 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	NC1	passive	Normally-closed throw of SPDT channel 1. Connected to COM1 when IN = 0 (and EN = 0). Rail-to-rail analog signal, 0 to V+, typ. 0.4 Ω on-resistance.
2	IN	input	Logic control input, shared by all four SPDT channels. Selects NC path when low and NO path when high (with EN low). VINL <= 0.3 V, VINH >= 1.2 V; CMOS-compatible.
3	NO2	passive	Normally-open throw of SPDT channel 2. Connected to COM2 when IN = 1 and EN = 0. Rail-to-rail analog signal, 0 to V+.
4	COM2	passive	Common (pole) terminal of SPDT channel 2. Routed to NC2 or NO2 by IN with EN low; both throws off when EN high.
5	NC2	passive	Normally-closed throw of SPDT channel 2. Connected to COM2 when IN = 0 and EN = 0.
6	GND	power_in	Device ground reference. All analog signals and control-logic thresholds are referenced to this pin.
7	NO3	passive	Normally-open throw of SPDT channel 3. Connected to COM3 when IN = 1 and EN = 0.
8	COM3	passive	Common (pole) terminal of SPDT channel 3. Routed to NC3 or NO3 by IN with EN low.
9	NC3	passive	Normally-closed throw of SPDT channel 3. Connected to COM3 when IN = 0 and EN = 0.
10	EN	input	Active-low enable. When EN = 0 the four channels follow IN (break-before-make between NC and NO); when EN = 1 all NC and NO paths are opened regardless of IN. VINL <= 0.3 V, VINH >= 1.2 V.
11	NO4	passive	Normally-open throw of SPDT channel 4. Connected to COM4 when IN = 1 and EN = 0.
12	COM4	passive	Common (pole) terminal of SPDT channel 4. Routed to NC4 or NO4 by IN with EN low.
13	NC4	passive	Normally-closed throw of SPDT channel 4. Connected to COM4 when IN = 0 and EN = 0.
14	V+	power_in	Single positive supply, 1.8 V to 5.5 V. Sets the maximum rail-to-rail analog signal range on all NC/NO/COM pins; typical quiescent current 29 uA.
15	NO1	passive	Normally-open throw of SPDT channel 1. Connected to COM1 when IN = 1 and EN = 0.
16	COM1	passive	Common (pole) terminal of SPDT channel 1. Routed to NC1 or NO1 by IN with EN low.
