... 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 ADV7129 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 ...

... The ADV7129 is a very highly integrated monolithic silicon device. This high level of integration inevitably leads to consid- eration of thermal and environmental conditions which the ADV7129 must operate in. Reliability of the device is enhanced by keeping it as cool as possible. In order to avoid destructive damage to the device, the absolute maximum junction tempera- ture must never be exceeded ...
