CD4051TA16.TR

The CD4051 is an 8-channel analog multiplexer/demultiplexer with three address inputs (S1 to S3), an active-low enable input (E̅), eight independent inputs/outputs (Y0 to Y7), and a 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 to the common input/output (Z). When E̅ is low, one of the eight switches is selected (low-impedance ON state) via S1 to S3. When E̅ is high, all switches are in the high-impedance OFF state, regardless of the states of S1 to S3. If break-before-make switching 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 3 V to 9 V. The analog input/output swing (Y0 to Y7 and Z) can range between VDD as the positive limit and VEE as the negative limit. VDD − VEE must not exceed 9 V. Unused inputs must be connected to VDD, VSS, or another input. When used as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground). VEE and VSS are the supply voltage connections for the switches.
