RS2228XN

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

RS2228XN 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	S	input	Select input that sets the signal path when OE is low; it must be held at VIH (1.6 V) or VIL (0.5 V) and should be pulled to V+ or GND rather than left floating.
2	HSD1+	passive	High-speed USB data port 1 positive terminal, an analog I/O that must stay within 0 V to V+ (rail-to-rail), with continuous current limited to ±100 mA.
3	HSD2+	passive	High-speed USB data port 2 positive terminal, an analog I/O that must stay within 0 V to V+ (rail-to-rail), with continuous current limited to ±100 mA.
4	D+	passive	Common USB D+ switch terminal that connects to HSD1+ or HSD2+ depending on S and OE, with the same 0 V to V+ analog range and ±100 mA continuous current limit.
5	GND	power_in	Ground reference for the device, to which the digital inputs and analog signal levels are referenced (0 V).
6	D-	passive	Common USB D- switch terminal that connects to HSD1- or HSD2- depending on S and OE, with the same 0 V to V+ analog range and ±100 mA continuous current limit.
7	HSD2-	passive	High-speed USB data port 2 negative terminal, an analog I/O that must stay within 0 V to V+ (rail-to-rail), with continuous current limited to ±100 mA.
8	HSD1-	passive	High-speed USB data port 1 negative terminal, an analog I/O that must stay within 0 V to V+ (rail-to-rail), with continuous current limited to ±100 mA.
9	OE	input	Active-low output enable that places both signal paths in high impedance when driven high; it must be held at a valid logic level and should not float.
10	V+	power_in	Positive supply, specified from 1.8 V to 5.5 V (absolute maximum 6 V to GND), which must be decoupled per the datasheet.
