Load Circuit for Digital Output Timing Specifications Digital Output Voltage to GND –0.3 V to V + 0.3 V DD Stresses at or above those listed under Absolute Maximum V to GND –0.3 V to V + 0.3 V REF DD Ratings may cause permanent damage to the product. This is a Input Current to Any Pin Except Supplies1 ±10 mA stress rating only; functional operation of the product at these Operating Temperature Range or any other conditions above those indicated in the operational Commercial (B Version) –40°C to +85°C section of this specification is not implied. Operation beyond Storage Temperature Range –65°C to +150°C the maximum operating conditions for extended periods may Junction Temperature 150°C affect product reliability. θ Thermal Impedance 211.5°C/W JA θ Thermal Impedance 91.99°C/W JC
