DESCRIPTION

The HEF4052B is a dual 4-channel analogue multiplexer/demultiplexer with common channel select logic. Each multiplexer/demultiplexer has four independent inputs/outputs (Y0 to Y3) and a common input/output (Z). The common channel select logic includes two address inputs (A0 and A1) and an active LOW enable input(E).

Both multiplexers/demultiplexers contain four bidirectional analogue switches, each with one side connected to an independent input/output (Y0 to Y3) and the other side connected to a common input/output (Z).
