CD4051HAEN

CD4051H 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 one common input/output (Z). The device contains eight bidirectional analog switches, each with one terminal connected to an independent input/output (Y0 to Y7) and the other terminal 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 a high-impedance OFF state, independent of the states 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 18V. The swing of the analog inputs/outputs (Y0 to Y7 and Z) can range from VDD as the positive limit to VEE as the negative limit. VDD−VEE must not exceed 18V. 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.
