Note 2. Stresses beyond those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. These

are stress ratings only, and functional operation of the device at these or any other condition beyond those indicated

in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may

affect device reliability.

Note 3. JA is measured under natural convection (still air) at TA = 25°C with the component mounted on a low effective-

thermal-conductivity two-layer test board on a JEDEC thermal measurement standard.

JC is measured at the exposed

pad of the package.

Note 4. Devices are ESD sensitive. Handling precautions are recommended.

Note 5. The device is not guaranteed to function outside its operating conditions.
