Notes:
1. All –3 speed grades have been discontinued.
2. Delays based on 50 pF loading.
3. 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.
4. Delays based on 35 pF loading.
