RS2254XQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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 A IN/OUT bidirectional Switch A analog signal terminal (in/out). Bidirectional analog pass connection to pin 2 when Switch A control (pin 13) is HIGH. Signal range GND to VCC; RON ≈ 24 Ω typ at VCC=5 V.
2 A OUT/IN bidirectional Switch A analog signal terminal (out/in). Bidirectional analog pass connection to pin 1 when Switch A control (pin 13) is HIGH.
3 B OUT/IN bidirectional Switch B analog signal terminal (out/in). Bidirectional analog pass connection to pin 4 when Switch B control (pin 5) is HIGH.
4 B IN/OUT bidirectional Switch B analog signal terminal (in/out). Bidirectional analog pass connection to pin 3 when Switch B control (pin 5) is HIGH.
5 B input Digital control input for Switch B. HIGH (VIH ≥ 1.7 V) turns Switch B ON; LOW (VIL ≤ 0.5 V) turns it OFF. Must not be left floating - tie to VCC or GND when unused.
6 C input Digital control input for Switch C. HIGH turns Switch C ON; LOW turns it OFF. VIH ≥ 1.7 V, VIL ≤ 0.5 V. Must not be left floating.
7 GND power_in Device ground / negative supply reference. Sets the lower analog signal-range limit for all four switches.
8 C IN/OUT bidirectional Switch C analog signal terminal (in/out). Bidirectional analog pass connection to pin 9 when Switch C control (pin 6) is HIGH.
9 C OUT/IN bidirectional Switch C analog signal terminal (out/in). Bidirectional analog pass connection to pin 8 when Switch C control (pin 6) is HIGH.
10 D OUT/IN bidirectional Switch D analog signal terminal (out/in). Bidirectional analog pass connection to pin 11 when Switch D control (pin 12) is HIGH.
11 D IN/OUT bidirectional Switch D analog signal terminal (in/out). Bidirectional analog pass connection to pin 10 when Switch D control (pin 12) is HIGH.
12 D input Digital control input for Switch D. HIGH turns Switch D ON; LOW turns it OFF. VIH ≥ 1.7 V, VIL ≤ 0.5 V. Must not be left floating.
13 A input Digital control input for Switch A. HIGH turns Switch A ON; LOW turns it OFF. VIH ≥ 1.7 V, VIL ≤ 0.5 V. Must not be left floating.
14 VCC power_in Positive supply input. Recommended operating range 2.5 V to 5.5 V; absolute maximum 6 V. Bypass locally to GND (pin 7); sets the upper analog signal-range limit.
