NOTES:
2874 tbl 08
1. All timings referenced to 1.5V, with a rise and fall time of less than 2.5ns.
2. All outputs tested with 25pF loading.
3. The AC values listed here reference timing diagrams contained in the R3051 Family Hardware User's Manual.
4. Guaranteed by design.
5. This parameter is used to derate the AC timings according to the loading of the system. This parameter provides a deration for loads over the specified
test condition; that is, the deration factor is applied for each 25pF over the specified test load condition.
