Note 1. 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 2.

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

conductivity four-layer test board on a JEDEC 51-7 thermal measurement standard.
