ESTEK IW4066B

IW4066B
Description
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

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range
GNDᆪ (VIN or VOUT)ᆪ VCC.
CC
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or
).
V
Unused outputs must be left open.
