RS2103XC6

Jiangsu RUNIC Tech · Analog Switches, Multiplexers · SOT-363

RS2103XC6 from Jiangsu RUNIC Tech, in a SOT-363. 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 IN input Digital control pin (TTL/CMOS compatible); inputs are diode-clamped to the supply rails, and signals swinging more than 0.3V beyond the rails should be limited to 10mA or less.
2 V+ power_in Power supply, specified from 1.8V to 5.5V; absolute maximum V+ is 6.0V.
3 GND power_in Ground reference for the device.
4 NC unconnected Normally-closed analog terminal, connected to COM when IN is 0 (analog signal range 0 to V+).
5 COM passive Common analog terminal; analog signal range is 0 to V+, continuous current limit ±500mA and peak ±800mA.
6 NO passive Normally-open analog terminal, connected to COM when IN is 1 (analog signal range 0 to V+).
