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).

With E LOW, one of the four switches is selected (low impedance ON-state)

by A0 and A1. With E HIGH, all switches are in the high impedance OFF-state, independent of A0 and A1.

VDD and VSS are the supply voltage connections for the digital control

inputs (A0, A1 and E). The VDD to VSS range is 3 to 15 V. The analogue

inputs/outputs (Y0 to Y3, 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).

Supply voltage (with reference to VDD)

VEE

−18 to + 0,5 V

Note

1.To avoid drawing VDD current out of terminal Z, when switch current flows into terminals Y, the voltage drop across the bidirectional switch must not exceed 0,4 V. If the switch current flows into terminal Z, no VDD current will flow out of terminals Y, in this case there is no limit for the voltage drop across the switch, but the voltages at Y and Z may not exceed VDD or VEE.
