Texas Instruments  CD4066BNSR

The CD4066B device is a quad bilateral switch intended for the transmission ormultiplexing of analog or digital signals. It is pin-for-pin compatible with the CD4016B device,but exhibits a much lower on-state resistance. In addition, the on-state resistance is relativelyconstant over the full signal-input range.

The CD4066B device consists of four bilateral switches, each with independent controls.Both the p and the n devices in a given switch are biased on or off simultaneously by the controlsignal. As shown in Figure 17, the well of the n-channel device on eachswitch is tied to either the input (when the switch is on) or to VSS (whenthe switch is off). This configuration eliminates the variation of the switch-transistor thresholdvoltage with input signal and, thus, keeps the on-state resistance low over the fulloperating-signal range.

The advantages over single-channel switches include peak input-signal voltage swingsequal to the full supply voltage and more constant on-state impedance over the input-signal range.However, for sample-and-hold applications, the CD4016B device is recommended.
