DESCRIPTION
The HEF4053B is a triple 2-channel analogue
multiplexer/demultiplexer with a common enable input (E).
Each multiplexer/demultiplexer has two independent
inputs/outputs (Y0 and Y1), a common input/output (Z),
and select inputs (Sn). Each also contains two-bidirectional
analogue switches, each with one side connected to an
independent input/output (Y0 and Y1) and the other side
connected to a common input/output (Z).
With E LOW, one of the two switches is selected (low
impedance ON-state) by Sn. With E HIGH, all switches are
in the high impedance OFF-state, independent of SA to SC.
VDD and VSS are the supply voltage connections for the
digital control inputs (SA to SC and E).
The VDD to VSS range is 3 to 15 V. The analogue
inputs/outputs (Y0, Y1 and Z) can swing between VDD as a
positive limit and VEE as a negative limit. VDD−VEE may not
exceed 15 V.
For operation as a digital multiplexer/demultiplexer, VEE is
connected to VSS (typically ground).

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.
