Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Plastic Package 2Transient currents of up to 100 mA will not cause SCR latchup. θJA Thermal Impedance . 74°C/W 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. WARNING! Although this device features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD ESD SENSITIVE DEVICE precautions are recommended to avoid performance degradation or loss of functionality.
