MSI
8-channel analogue multiplexer/demultiplexer
and the other side connected to a
common input/output (Z).
The analogue inputs/outputs (Y0 to
Y7, and Z) can swing between VDD as
a positive limit and VEE as a negative
limit. VDD−VEE may not exceed 15 V.
DESCRIPTION
The HEF4051B is an 8-channel
analogue multiplexer/demultiplexer
with three address inputs (A0 to A2),
an active LOW enable input (E), eight
independent inputs/outputs (Y0 to Y7)
and a common input/output (Z).
With E LOW, one of the eight
switches is selected (low impedance
ON-state) by A0 to A2. With E HIGH,
all switches are in the high impedance
OFF-state, independent of A0 to A2.
For operation as a digital
multiplexer/demultiplexer, VEE is
connected to VSS (typically ground).
VDD and VSS are the supply voltage
connections for the digital control
inputs (A0 to A2, and E).
The device contains eight
bidirectional analogue switches, each
with one side connected to an
independent input/output (Y0 to Y7)
The VDD to VSS range is 3 to 15 V.

Note
1. To avoid drawing VDD current out of terminal Z, when switch current flows into terminals Y, the voltage drop across
the bidirectional switch must not exceed 0,4 V. If the switch current flows into terminal Z, no VDD current 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 VDD or VEE
