HEF4067B

The HEF4067B is a 16-channel analogue multiplexer/demultiplexer with four address inputs (A₀ to A₃), an active LOW enable input (E) , sixteen independentinputs/outputs (Y₀ to Y₁₅)and a common input/output (Z).

The HEF4067B contains sixteen bidirectional analogue switches, each with one side connected to an independent input/output (Y₀ to Y₁₅)and the other side connected to the common input/output (Z).With E LOW, one of the sixteen switches is selected (low impedance ON-state) by A₀to A₃.All unselected switches are in the high impedance OFF-state. With E HIGH all switches are in the high impedance OFF-state, independent of A₀ to A₃.The analogue inputs/outputs (_Y0 to Y₁₅and Z) can swing between V_DDas a positive limit and V_SS as a negative limit. V_DD to V_SS may not exceed 15 V.
