One Bit Toggling, 50% Duty Cycle

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 4: Guaranteed, but not tested.
