Standard ICs
8-channel analog multiplexer /
demultiplexer
BU4051BC / BU4051BCF / BU4051BCFV
The BU4051BC, BU4051BCF and BU4051BCFV are analog multiplexers / demultiplexers which use three-input digital signals for control via an 8-channel analog switch.
These products feature high on / off output voltage ratio and low crosstalk between analog switches.
