ESD CAUTION
Operating Temperature Range −40°C to +125°C Storage Temperature Range −65°C to +150°C Junction Temperature 150°C ESD Human Body Model (HBM) 1.5 kV Field Induced Charged Device 500 V Model (FICDM) 1 The digital input pins include the following: AS0, RESET, AS1, SCL, SDA, and CONVST/GPO1. 2 The digital output pins include: ALERT/BUSY/GPO0, GPO2, and SDA. 3 Transient currents of up to 100 mA do not cause SCR latch-up. 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.
