I just wanted to confirm that I don't need a current limiting resistor on the input of a 74XX chip.
I am currently testing on a 7404 and it seems to work fine if I connect up one of the inputs directly to the +5V power supply. Just wanted to make sure I am not risking burning out the chip. From what I can tell from reading the datasheets they have lots of internal resistors inside of them.
Thanks and sorry if this is a complete newbie question.
I have seen conflicting answers on the web.
