Hi,
I am planning to do DC drop for my board as part of Power Integrity analysis.
I am calculating current requirements of the ICs.
For logic IC (Eg: SN74LCV245APW) total current is Static and Dynamic current requirements.
For dynamic should I consider only switching current(C*V*F*N) or only IO currents(IOH & IIL) or both switching & IO currents.
If I do this for all the 8 channels, am I over rating my current requirements. What is the best way to calculate the current requirement of a logic device like level translator or buffer.
Regards,
