General Purpose CMOS Logic IC
8ch Analog Multiplexer/Demultiplexer
BU4051BC BU4051BCF BU4051BCFV
General Description
The BU4051BC, BU4051BCF, BU4051BCFV are
multiplexers/demultiplexers with capabilities of selection
and mixture of analog signal and digital signal.
This
series
are
configured
with
8channels
input/output.The digital signal of the control terminal
turns on the corresponding switch of each channel. The
large amplitude 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.
