NOTES:

8. Limits tested 100%.

9. 3.3V Min is at 3.6V, Max is at 3V.

10. 5V Min is at 5.5V, Max is at 4.5V.

11. CPD is used to determine the dynamic power consumption per function.

AC: PD = VCC

2 f

i (CPD + CL)

ACT: PD = VCC

2 f

i (CPD + CL) + VCC ∆ICC where fi = input frequency, CL = output load capacitance, VCC = supply voltage.
