Jiangsu RUNIC Tech · Analog Switches, Multiplexers · TSSOP-16
RS2251XTSS16-Q1 from Jiangsu RUNIC Tech, in a TSSOP-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 | X4 | passive | Analog switch input X4; analog signal range is GND to VCC, and input and output pins are interchangeable so signals pass in either direction. |
| 2 | X6 | passive | Analog switch input X6; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 3 | X | passive | Common analog switch output X, which carries the selected channel (X0-X7) and is interchangeable with the inputs. |
| 4 | X7 | passive | Analog switch input X7; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 5 | X5 | passive | Analog switch input X5; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 6 | ENABLE | input | Digital enable input, normally connected to GND; a logic 1 on this pin turns all channels off (function table shows NONE). |
| 7 | NC | unconnected | No connect; leave this pin unconnected. |
| 8 | GND | power_in | Ground, connect to digital ground. |
| 9 | C | input | Digital address C input (binary channel select, MSB); unused digital inputs must be held at VCC or GND for proper operation. |
| 10 | B | input | Digital address B input (binary channel select); unused digital inputs must be held at VCC or GND for proper operation. |
| 11 | A | input | Digital address A input (binary channel select, LSB); unused digital inputs must be held at VCC or GND for proper operation. |
| 12 | X3 | passive | Analog switch input X3; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 13 | X0 | passive | Analog switch input X0; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 14 | X1 | passive | Analog switch input X1; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 15 | X2 | passive | Analog switch input X2; analog signal range is GND to VCC, and signals pass equally well in either direction. |
| 16 | VCC | power_in | Positive analog and digital supply voltage input, specified at 2.5 V to 5.5 V with absolute maximum of 6 V. |
