Standard ICs
Quad 2-input / 2-output analog switch
BU9761FS
The BU9761FS are analog switches with four circuits each, two for input and two for output. Depending on the status
of the SELECT pin, the two input signals can be switched to either of two output pins. In addition, the EN pin can be
used to set the output status to high impedance.
