I am using ULN2003a to drive multiple LED and controlling it directly through controller. I want to know what is the min voltage I can apply at the imput(base) terminal to start the function. Or say V(IH) value?

Hi Abhishek,
What will be the output current? Please see the VI(on) parameter in the ULN2003A data sheet, this is the V(IH) parameter.
Thanks,
