FSUSB30MUX

onsemi · USB Converters · MSOP-10

FSUSB30MUX from onsemi, in a MSOP-10. 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 S input Select input. Chooses which USB source pair is connected to D+/D-: S=L selects HSD1+/HSD1-; S=H selects HSD2+/HSD2- (when /OE is low). CMOS-level input, VIH ≥ 1.3V @ VCC=3.0-3.6V; must not float.
2 HSD1+ bidirectional Hi-Speed USB source 1 positive data line. Analog switch port routed to D+ when S=L and /OE=L. Bidirectional passive USB 2.0 differential data line, VSW range 0V to VCC.
3 HSD2+ bidirectional Hi-Speed USB source 2 positive data line. Analog switch port routed to D+ when S=H and /OE=L. Bidirectional passive USB 2.0 differential data line, VSW range 0V to VCC.
4 D+ bidirectional Common USB positive data line. Connects to the selected HSDn+ port through the DPDT switch. Withstands up to 4.3V even when VCC=0V (power-off protection).
5 GND power_in Ground reference. 0V return for VCC and all signal references.
6 D- bidirectional Common USB negative data line. Connects to the selected HSDn- port through the DPDT switch. Withstands up to 4.3V even when VCC=0V (power-off protection).
7 HSD2- bidirectional Hi-Speed USB source 2 negative data line. Analog switch port routed to D- when S=H and /OE=L. Bidirectional passive USB 2.0 differential data line, VSW range 0V to VCC.
8 HSD1- bidirectional Hi-Speed USB source 1 negative data line. Analog switch port routed to D- when S=L and /OE=L. Bidirectional passive USB 2.0 differential data line, VSW range 0V to VCC.
9 ~{OE} input Bus switch enable, active-low. When /OE=L the DPDT switch is enabled and connects D+/D- to the selected HSDn pair; when /OE=H both channels are disconnected (high-impedance). CMOS input, must not float.
10 VCC power_in Supply voltage input. Recommended operating range 3.0V to 4.3V (absolute max 4.6V). Typical quiescent supply current ICC ≤ 1µA.
