1. See test circuit and waveforms.

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

3. 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%.
