3. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal.
4. Enable is defined as the propagation delay from the 50% point of a negative transition on EN to the 50% point of a positive transition on Q (or a
5. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.
6. The set-up time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than
7. The hold time is the minimum time that EN must remain asserted after a negative going IN or a positive going IN to prevent an output response
8. The release time is the minimum time that EN must be de-asserted prior to the next IN/IN transition to ensure an output response that meets the
