NOTES:

8. Limits tested at 100%.

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

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

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

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.
