(PCB) design and operating environment. VDD to VSS 7 V Careful attention to PCB thermal design is required. VDD to GND −0.3 V to +7 V θJA is the natural convection, junction to ambient thermal VSS to GND +0.3 V to −3.5 V resistance measured in a one cubic foot sealed enclosure. θJC is Analog Inputs1 VSS −0.3 V to VDD +0.3 V or the junction to case thermal resistance. 30 mA, whichever occurs first Digital Inputs1 –0.3 V to VDD +0.3 V or 30 mA,

ESD CAUTION
1 Overvoltages at the DIN pin, Sx, or Dx are clamped by internal diodes. Limit current to the given maximum ratings. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev.
