Notes:

1. Propagation Delays and Enable/Disable times are with Vcc = 3.3V ±0.3V, normal range.

For Vcc = 2.7V, extended range, all Propagation Delays and Enable/Disable times should

be degraded by 20%.

2. See test circuit and wave forms.

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

4. This parameter is guaranteed but not production tested.

5. Skew between any two outputs, of the same package, switching in the same direction.

This parameter is guaranteed by design.
