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 Features Operating Voltage Range: 3.0 to 18 V Maximum input current of 1 at 18 V over full packageutemperature range ;100 nA at 18 V and 25 C A Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 14 1 SOP 14 2.0 V min @ 10.0 V supply 14 1 2.5 V min @ 15.0 V supply DIP Package Logic Diagram 1 14 2 Pin Assignment YA XA 13 A ON/OFF CONTROL 4 3 XA YA YB YB CC A ON/OFF CONTROL D ON/OFF XB B ON/OFF CONTROL 5 XB XD B ON/OFF CONTROL 8 9 XC C ON/OFF CONTROL C ON/OFF CONTROL YC GND 6 11 XD YD YC XC 10 YD Function Table 12 D ON/OFF CONTROL PIN 14 = V DD PIN 7 = On/Off Control Input State of Analog Switch L Off H On BEIJING ESTEK ELECTRONICS CO.,LTD 1 IW4066B Absolute Maximum Ratings Symbol Parameter Value Unit -0.5 to +20 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V VOUT IIN DC Input Current, per Pin PD Power Dissipation in Still Air, Plastic PD SOIC Package+ Power Dissipation per Output Transistor Tstg TL DIP+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) + - 10 mA 750 500 mW 100 mW -65 to +150 °C 260 °C Maximum Ratings are those values beyond which damage to the device may occur.

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.
