8-channel analogue multiplexer/demultiplexer
DESCRIPTION
The HEF4051B is an 8-channel
analogue multiplexer/demultiplexer
with three address inputs (A0to A2),
an active LOW enable input (E), eight
independent inputs/outputs (Y0to Y7)
and a common input/output (Z).
The device contains eight
bidirectional analogue switches, each
with one side connected to an
independent input/output (Y
to Y7)
0
and the other side connected to a
common input/output (Z).
E LOW, one of the eight
With
switches is selected (low impedance
ON-state) by A0to A2. With E HIGH,
all switches are in the high impedance
OFF-state, independent of A0to A2.
VDDand VSSare the supply voltage
connections for the digital control
inputs (A0to A2, and E).
The VDDto VSSrange is 3 to 15 V.
HEF4051B
MSI
The analogue inputs/outputs (Y0to
Y7, and Z) can swing between VDDas
a positive limit and VEEas a negative
limit. VDD−VEEmay not exceed 15 V.
For operation as a digital
multiplexer/demultiplexer, VEEis
connected to VSS(typically ground).

Note
1. To avoid drawing V
current out of terminal Z, when switch current flows into terminals Y, the voltage drop across
DD
the bidirectional switch must not exceed 0,4 V. If the switch current flows into terminal Z, no VDDcurrent will flow out
of terminals Y, in this case there is no limit for the voltage drop across the switch, but the voltages at Y and Z may
not exceed VDDor VEE.
