HEF4051BT(LX)

The HEF4051 is an 8-channel analog multiplexer/demultiplexer with three address inputs (S1 to S3), one 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 the common input/output (Z). When E is LOW, one of the eight switches is selected (low-impedance ON state) via S1 to S3. When E is HIGH, all switches are in the high-impedance OFF state, independent of S1 to S3. If break-before-make operation is required, the enable input must be used. VDD and VSS are the supply voltage connections for the digital control inputs (S1 to S3, and E). The VDD to VSS range is 3V to 9V. The analog inputs/outputs (Y0 to Y7, and Z) can swing between VDD as the positive limit and VEE as the negative limit. VDD − VEE must not exceed 9V. Unused inputs must be connected to VDD, VSS, or another input. When operating as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground). VEE and VSS are the supply voltage connections for the switches.
