Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed
circuit board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the
declared operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device
specification limit values are applied individually under normal operating conditions and not valid simultaneously.
