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).
The device contains eight
bidirectional analogue switches, each
with one side connected to an
independent input/output (Y0 to Y7)
and the other side connected to 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.
VDD and VSS are the supply voltage
connections for the digital control
inputs (A0 to A2, and E).
The VDD to VSS range is 3 to 15 V.
The analogue inputs/outputs (Y0 to
Y7, and Z) can swing between VDD as
a positive limit and VEE as a negative
limit. VDDVEE may not exceed 15 V.
For operation as a digital
multiplexer/demultiplexer, VEE is
connected to VSS (typically ground).
