Notes:
1. Delays based on 50 pF loading.
2. To obtain the slew rate, substitute the appropriate Delta value, load capacitance, and the VCCI value into the following equation:
Slew Rate [V/ns] = (0.1*VCCI – 0.9*VCCI)/ (Cload * dT[LH|HL|HLS])
where Cload is the load capacitance driven by the I/O in pF
dT[LH|HL|HLS] is the worst case delta value from the datasheet in ns/pF.
3. Delays based on 35 pF loading.
