Absolute maximum ratings represent the values which cannot be exceeded even for a moment 4. If you should intend to use this IC continuously under high temperature, high current, high voltage, or drastic temperature change, even if it is used within the range of absolute maximum ratings or operating conditions, there is a possibility of decrease reliability. Please contact us for a confirmation © Semiconductor Components Industries, LLC, 2015 ORDERING INFORMATION Ordering Code: LB11862MC-AH Storage temperature Tstg C -55 to +150 1. Stresses exceeding those listed in the Absolute Maximum Rating 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.
