VDD2, VIO −0.3 V to +2.1 V Digital Inputs to GND −0.3 V to VIO + 0.3 V Digital Outputs to GND −0.3 V to VIO + 0.3 V Input Current to Any Pin ±10 mA Except Supplies Operating Temperature −40°C to +85°C Range (Commercial) Storage Temperature Range −65°C to +150°C Junction Temperature 150°C ESD Ratings Human Body Model 4 kV Machine Model 200 V Field-Induced Charged- 1.25 kV Device Model 1 Transient currents of up to 100 mA do not cause SCR latch-up. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Rev.
