Load Circuit for Data Access Time and Bus Latch-Up for ID Pin2 . ≤ –70 mA Relinquish Time Latch-Up for All Other Pins . ≥ –110 mA NOTES 1Stresses above those listed under Absolute Maximum Ratings may cause perma- nent 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. 2Correct usage of the ID pin will prevent any latch-up from occurring. In an application, the ID pin should be either tied to VDD via a 100 kΩ resistor or left open circuit. If the application complies with this recommendation, the ID pin will never see –70 mA.

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 the AD7314 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.
