CD4066BMS is a quad bilateral switch intended for the
transmission or multiplexing of analog or digital signals. It is
pin for pin compatible with CD4016B, but exhibits a much
lower on state resistance. In addition, the on-state resistance
is relatively constant over the full input signal range.
The CD4066BMS consists of four independent bilateral
switches. A single control signal is required per switch. Both
the p and the n device 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 either tied
to 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. For sample and hold applications, however, the
CD4016B is recommended.
