ROHM BU4551BFV, BU4551BF, BU4551B Datasheet
1
Standard ICs
Quad 2-channel analog multiplexer /
demultiplexer
BU4551B / BU4551BF / BU4551BFV
The BU4551B, BU4551BF, and BU4551BFV are multiplexers / demultiplexers capable of selecting and combining
analog signals and digital signals with a configuration of 2 ch × 4.
Control signals are used to turn on the switch of the corresponding channel. In addition, even if the logical amplitude
(V
DD-VSS) of the control signal is low, signals with a large amplitude (VDD-VEE) can be switched.
In addition, as each switch has a low ON resistance, it can be connected to a low impedance circuit.
