Notes:
1. This parameter is sampled. Vdd = +1.8V ±0.1V, VddQ = +1.8V ±0.1V, Vref = Vss, f = 100
2. The capacitance per ball group will not differ by more than this maximum amount for
3. ΔC are not pass/fail parameters; they are targets.
4. Reduce MAX limit by 0.25pF for -25, -25E, and -187E speed devices.
5. Reduce MAX limit by 0.5pF for -3, -3E, -25, -25E, and -187E speed devices.
