Extended exposure to stresses beyond the Recomme nded Operating Ranges limits mayaffect device reliability. Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product per formance may not be indicated by the Electrical Characteristics if operated under different conditions.
