Note 1: 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 2: Either voltage limit or current limit is sufficient to protect inputs.
Note 3: Guaranteed but not tested.
Note 4: For 8-bit toggling. ICCD < 1.4 mA/MHz.
