Overview

The HEF4051BT is a 8-channel Analog Multiplexer/Demultiplexer with three address inputs (S1 to S3), an active low enable input (E\), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). The device contains eight bidirectional analog switches, each with one side connected to an independent input/output (Y0 to Y7) and the other side connected to a common input/output (Z). With E\ low, one of the eight switches is selected (low-impedance on-state) by S1 to S3. With E\ high, all switches are in the high-impedance OFF-state, independent of S1 to S3. If break before make is needed, then it is necessary to use the enable input. VDD and VSS are the supply voltage connections for the digital control inputs (S1 to S3 and E\). The VDD to VSS range is 3 to 15 V. The analog inputs/outputs (Y0 to Y7 and Z) can swing between VDD as a positive limit and VEE as a negative limit. VDD - VEE may not exceed 15V. Unused inputs must be connected to VDD, VSS or another input.
