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/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.
