Parameter Rating
may cause permanent damage to the device. This is a stress V rating only; functional operation of the device at these or any DD to GND −0.3 V to +7 V Analog Input Voltage to GND −0.3 V to V other conditions above those indicated in the operational DD + 0.3 V Digital Input Voltage to GND −0.3 V to +7 V section of this specification is not implied. Exposure to absolute Digital Output Voltage to GND −0.3 V to V maximum rating conditions for extended periods may affect DD + 0.3 V Input Current to Any Pin Except Supplies1 ±10 mA device reliability. Operating Temperature Range Commercial Range (A, B Versions) –40°C to +85°C Military Range (S Version) −55°C to +125°C Storage Temperature Range −65°C to +150°C Junction Temperature 150°C SOT-23 Package θJA Thermal Impedance 230°C/W θJC Thermal Impedance 92°C/W Lead Temperature, Soldering Reflow (10 sec to 30 sec) 235 (0/+5)°C Pb-free Temperature Soldering Reflow 255 (0/+5)°C ESD 3.5 kV 1Transient currents of up to 100 mA do not cause SCR latch-up.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.
