The HEF4052B-Q100 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/output (nZ). The common channel select logic includes
two select inputs (S1 and S2) and an active LOW enable input (E). Both
multiplexers/demultiplexers contain four bidirectional analog switches, each with one side
connected to an independent input/output (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, independent 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 connected to VDD, VSS, or another input. For
operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically
ground). VEE and VSS are the supply voltage connections for the switches.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
