3 / 11 page 3 www.fairchildsemi.com Absolute Maximum Ratings(Note 2) Recommended Operating Conditions Note 2: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied. Note 3: Either voltage limit or current limit is sufficient to protect inputs. DC Electrical Characteristics Note 4: For 8 bits toggling, ICCD 0.8 mA/MHz. Note 5: Guaranteed, but not tested.
