2. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating
device performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route
timing is based on actual routing delay measurements performed on the device prior to shipment.
3. Delays based on 35 pF loading, except t

. For t
ENZL
and t

the loading is 5 pF.
