8MHz, RL = 1kΩ

• Matched Control Input to Signal Output

Capacitance: Reduces Output Signal Transients

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.

The CD4066BMS is supplied in these 14-lead outline pack-
