GND – 0.5 to VAA NOTES 1Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2Analog output short circuit to any power supply or common can be of an indefinite duration. ORDERING GUIDE Temperature Package Package Model Range Description Option ADV7178KS 0 °C to +70°C Plastic Quad Flatpack S-44 ADV7177KS 0 °C to +70°C Plastic Quad Flatpack S-44 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 ADV7177/ADV7178 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, pr oper ESD precautions are recommended to avoid performance degradation or loss of functionality.

The junction-to-case thermal resistance (θ JC) is 18.8 °C/W. Care must be taken when operating the part in certain condi- tions to prevent overheating. Table I illustrates what conditions are to be used when using the part. Table I. Allowable Operating Conditions for ADV7177/ ADV7178 in 44-Lead PQFP Package Condition 5 V 3 V 3 DACs ON, Double 75R 1 No Yes 3 DACs ON, Low Power 2 Yes Yes 3 DACs ON, Buffered 3 Yes Yes 2 DACs ON, Double 75R No Yes 2 DACs ON, Low Power Yes Yes 2 DACs ON, Buffered Yes Yes NOTES 1DAC ON, Double 75R refers to a condition where the DACs are terminated into a double 75R load and low power mode is disabled. 2DAC ON, Low Power refers to a condition where the DACs are terminated in a double 75R load and low power mode is enabled. 3DAC ON, Buffered refers to a condition where the DAC current is reduced to 5 mA and external buffers are used to drive the video loads.
