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. |
