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 input-
signal voltage swings equal to the full supply voltage, and more constant
on-state impedance over the input-signal range.
