General Purpose CMOS Logic IC
Quad 2ch Analog Multiplexer/Demultiplexer
BU4551B BU4551BF BU4551BFV
General Description
The BU4551B, BU4551BF, BU4551BFV are
multiplexers/demultiplexers with capabilities of
selection and mixture of analog signal and digital
signal.
This series are configured with quad 2 channels
input/output. The digital signal of the control terminal
turns on the corresponding switch of each channel.
The large am plitude voltage (V
DD
-V
EE
) can be
switched by the control signal with small logical
amplitude voltage (V
DD
-V
SS
).

Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins
or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding
a fuse, in case the IC is operated over the absolute maximum ratings.
