NOTES:
1. Outputs loaded with 50
2. f
3. Differential propagation delay is defined as the delay from the crossing point of the differential input signals to the crossing point of the differential
4. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device operating at the same
5. The part-to-part skew is defined as the absolute worst case difference between any two delay paths on any two devices operating at the same
6. Set-up and hold time applies to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous applications,

set-up and hold time does not apply. OE set-up time is defined with respect to the rising edge of the clock. OE HIGH to LOW transition ensures
outputs remain disabled during the next clock cycle. OE LOW to HIGH transition enables normal operation of the next input clock.
