**Jiangsu RUNIC Tech** · Analog Switches, Multiplexers · MSOP-10

RS2058XN from Jiangsu RUNIC Tech, in a MSOP-10. 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 | COM1 | bidirectional | Common analog terminal of switch 1; analog signal range is 0 to V+ and continuous current is limited to ±300mA (peak ±500mA). |
| 2 | NC1 | unconnected | Normally-closed terminal of switch 1, connected to COM1 when IN1 is logic 0; continuous current is limited to ±300mA (peak ±500mA). |
| 3 | COM2 | bidirectional | Common analog terminal of switch 2; analog signal range is 0 to V+ and continuous current is limited to ±300mA (peak ±500mA). |
| 4 | NC2 | unconnected | Normally-closed terminal of switch 2, connected to COM2 when IN2 is logic 0; continuous current is limited to ±300mA (peak ±500mA). |
| 5 | GND | power_in | Ground reference pin for the device. |
| 6 | IN2 | input | Digital control input for switch 2; VINH minimum is 1.5 V and VINL maximum is 0.6 V at 5 V supply, and unused digital inputs must be held at VIO or GND. |
| 7 | NO2 | passive | Normally-open terminal of switch 2, connected to COM2 when IN2 is logic 1; continuous current is limited to ±300mA (peak ±500mA). |
| 8 | IN1 | input | Digital control input for switch 1; VINH minimum is 1.5 V and VINL maximum is 0.6 V at 5 V supply, and unused digital inputs must be held at VIO or GND. |
| 9 | NO1 | passive | Normally-open terminal of switch 1, connected to COM1 when IN1 is logic 1; continuous current is limited to ±300mA (peak ±500mA). |
| 10 | V+ | power_in | Power supply pin; operating range is 1.8 V to 5.5 V and the absolute maximum is 6.0 V. |
