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.

4. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays

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