BL1530MSOP

BL Shanghai Belling · Analog Switches, Multiplexers · MSOP-10L

BL1530MSOP from BL Shanghai Belling, in a MSOP-10L. 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 Sel input Switch select input (TTL/CMOS compatible). With OEb=0, Sel=0 routes Dp/Dn to Dp1/Dn1; Sel=1 routes Dp/Dn to Dp2/Dn2. VIH ≥ 1.6V, VIL ≤ 0.5V at VCC=3.0-3.6V.
2 Dp1 bidirectional USB D+ data port 1 (analog switch throw for the positive USB signal to endpoint 1). Bidirectional; connected to Dp when OEb=0 and Sel=0.
3 Dp2 bidirectional USB D+ data port 2 (analog switch throw for the positive USB signal to endpoint 2). Bidirectional; connected to Dp when OEb=0 and Sel=1.
4 Dp bidirectional USB D+ common data bus pole. Routed to Dp1 or Dp2 based on Sel when OEb=0; disconnected when OEb=1.
5 GND power_in Ground reference for the device.
6 Dn bidirectional USB D− common data bus pole. Routed to Dn1 or Dn2 based on Sel when OEb=0; disconnected when OEb=1.
7 Dn2 bidirectional USB D− data port 2 (analog switch throw for the negative USB signal to endpoint 2). Bidirectional; connected to Dn when OEb=0 and Sel=1.
8 Dn1 bidirectional USB D− data port 1 (analog switch throw for the negative USB signal to endpoint 1). Bidirectional; connected to Dn when OEb=0 and Sel=0.
9 OEb input Active-low output enable. OEb=1 disconnects both switches (Disconnect); OEb=0 enables the switch selected by Sel. TTL/CMOS compatible: VIH ≥ 1.6V, VIL ≤ 0.5V.
10 VCC power_in Positive supply, 2.3V to 5V operating range (absolute max 5.5V). Quiescent supply current ≤ 1uA at VCC=3V.
