CD4066BE

Product Summary

The CD4066B is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals.
It is pin-for-pin compatible with the CD4016B, but exhibits a much lower on-state resistance. In addition, the
on-state resistance is relatively constant over the full signal-input range.
The CD4066B 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 control signal. As shown in Figure 1, the well of the
n-channel device on each switch is tied to either the input (when the switch is on) or to VSS (when the switch
is off). This configuration eliminates the variation of the switch-transistor threshold voltage with input signal and,
thus, keeps the on-state resistance low over the full operating-signal range.
The advantages over single-channel switches include peak input-signal voltage swings equal to the full supply
voltage and more constant on-state impedance over the input-signal range. However, for sample-and-hold
applications, the CD4016B is recommended.
