NOTES:

1. 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%.

2. See test circuit and waveforms.

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

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

5. This parameter is guaranteed but not tested. Skew is not guaranteed when VCC < 0.3V.
