DESCRIPTION

The HEF4053B is a triple 2-channel analogue multiplexer/demultiplexer with a common enable input (E). Each multiplexer/demultiplexer has two independent inputs/outputs (Y0 and Y1), a common input/output (Z), and select inputs (Sn). Each also contains two-bidirectional analogue switches, each with one side connected to an independent input/output (Y0 and Y1) and the other side connected to a common input/output (Z).

With E LOW, one of the two switches is selected (low impedance ON-state) by Sn. With E HIGH, all switches are in the high impedance OFF-state, independent of SA to SC.

VDD and VSS are the supply voltage connections for the digital control inputs (SA to SC and E).

The VDD to VSS range is 3 to 15 V. The analogue inputs/outputs (Y0, Y1 and Z) can swing between VDD as a positive limit and VEE as a negative limit. VDD−VEE may not exceed 15 V.

For operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground).
