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.
