Quad analog switch
BU4066BC / BU4066BCF / BU4066BCFV
The BU4066BC, BU4066BCF, and BU4066BCFV each consist of four independent switches capable of controlling either
digital or analog signals. When Enable Input (CONT) is set to the "H" level, impedance is low (ON status) between switch
input and output, and when Enable Input (CONT) is set to the "L" level, impedance is high (OFF status). As the
BU4066BC has a good propagation characteristic, it can control large input voltage amplitudes. These switches can be
used in analog and digital signal switching and in chopper modulator and demodulator circuits.
