I'm using 74lsXX ICs for my 4-bit computer. I noticed that 74XX ICs have reverse current at the input; I know that the output of the IC allow the reverse input current flow back to it.
But I'm a bit confused because I don't know how to find the reverse current of the input and output.
I want to connect multiple inputs to an output and I want to know if the output can handle that much current. I've done some research and tried to find it in the datasheet but I can't find it. Does anyone know where to find it?
