Overview
TECHNICAL DATA IW4066B Quad Bilateral Switch High-Voltage Silicon-Gate CMOS The IW4066B is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals.
In addition, the on-state resistance is relatively constant over the full input-signal range.
The IW4066B 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 show in Fig.
1.
)The well of the n-channel device on each switch is either tied to the input when the switch is on or to GND 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 inputsignal voltage swings equal to the full supply voltage, and more constant on-state impedance over th...
