NOTES:

1. See test circuit and waveforms.

2. Minimum limits are guaranteed but not tested on Propagation Delays.

3. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.

and Enable/Disable times should be degraded by 20%.

5. This parameter is guaranteed but not tested.
