CD4051BDTR(XBLW)

CD4051 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 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 voltage range from VDD to VSS is 3V to 9V. The voltage on the analog inputs/outputs (Y0 to Y7 and Z) may 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 used as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground). VEE and VSS are the supply voltage connections for the switches.
