5. The full variation in the ratio of the maximum to minimum pullup and pulldown current will not exceed
1.7 for device drain to source voltages from 0.1 to 1.0.
6. The full variation in the ratio of the typical IBIS pullup to typical IBIS pulldown current should be unity
±
10%, for device drain to source voltages from 0.1 to 1.0. This specification is a design objective only.
7. These characteristics obey the SSTL_2 class II standard.
