* ESD senstive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection. Although the 82C931 features ESD protection circuitry, perma-nent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD pre-cautions are recommended to avoid performance degradation or loss of functionality.
