1. General description
The HEF4052B is a dual 4-channel analog multiplexer/demultiplexer with common
channel select logic. Each multiplexer/demultiplexer has four independent inputs/outputs
(nY0 to nY3) and a common input/o utput (nZ). The co mmon chan nel select logic includes
two select inputs (S1 and S2) and an active LOW enable input (E). Both
multiplexers/demu ltipl exers contain four b idirectio nal ana log switch es, each with one side
connected to an independent input/outpu t (nY0 to nY3) and the other side connected to a
common input/output (nZ). With E LOW, one of the four switches is selected
(low-impedance ON-state) by S1 and S2. With E HIGH, all switches are in the
high-impedance OFF-state, independe nt of S1 and S2. If break before make is needed,
then it is necessary to use the enable input.
VDD and VSS are the supply voltage connections for the digital control inputs (S1 and S2,
and E). The VDD to VSS range is 3 V to 15 V. The analog inputs/outputs (nY0 to nY3, and
nZ) can swing between VDD as a positive limit and VEE as a negative limit. VDD VEE may
not exceed 15 V. Unused inputs must be connec te d to VDD, VSS, or another input. Fo r
operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically
ground). VEE and VSS are the supply voltage connections for the switches.
