NOTES:
7. 5V: Min is at 5.5V, Max is at 4.5V.
5V: Min is at 5.25V for 0oC to 70oC, Max is at 4.75V for 0oC to 70oC, Typ is at 5V.
8. CPD, measured per function, is used to determine the dynamic power consumption.
PD (per package) = VCC ICC +∑ (VCC

VCC = supply voltage
∆lCC = flow through current x unit load
CL = output load capacitance
D = duty cycle of input high
