Exceeding the absolute maximum ratings may damage the device. 2. The device is not guaranteed to function outside its operating ratings. 3. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5k Ω in series with 100pF. 4. PD(MAX) = (TJ(MAX) – TA)/ θJA, where θJA depends upon the printed circuit layout. A 5-in 2 4 layer, 0.62”, FR-4 PCB with 2oz finish copper weight per layer is used for the θ JA. 5. Specification for packaged product only. |
