Logic Diagram MAXIMUM RATINGS Symbol Parameter Value Unit This device contains protection circuitry to guard against damage V Positive DC Supply Voltage (Referenced to GND) 0.5 to + 14.0 V CC due to high static voltages or electric V Analog Input Voltage (Referenced to GND) 0.5 to V + 0.5 V IS CC fields. However, precautions must be taken to avoid applications of any V Digital Input Voltage (Referenced to GND) 0.5 to V + 0.5 V in CC voltage higher than maximum rated I DC Current Into or Out of Any Pin 25 mA voltages to this highimpedance cir- cuit. For proper operation, V and in P Power Dissipation in Still Air, SOIC Package 500 mW D V should be constrained to the out TSSOP Package 450 range GND (V or V ) V . in out CC T Storage Temperature 65 to + 150 C Unused inputs must always be stg tied to an appropriate logic voltage T Lead Temperature, 1 mm from Case for 10 Seconds 260 C L level (e.g., either GND or V ). CC Unused outputs must be left open. Derating SOIC Package: 7 mW/ C from 65 to 125 C I/O pins must be connected to a TSSOP Package: 6.1 mW/ C from 65 to 125 C properly terminated line or bus.

Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability. *For voltage drops across the switch greater than 1.2 V (switch on), excessive V current may CC be drawn i.e., the current out of the switch may contain both V and switch input CC components. The reliability of the device will be unaffected unless the Maximum Ratings are exceeded.
