Hi. I want to connect an output from two 08M2 chips to a single input of an 18M2 so that either/or of the outputs will trigger the 18M2 input. I understand that I need to place a 1k resistor in series from each of the outputs but that will mean the two outputs are then connected together with a 2k resistance. I will also add a pull up (or pull down) resistor to the input of 18M2. So in effect I am just trying to achieve an OR gate. Will this work OK with all combinations of High and Low outputs from the 08M2s?
As an afterthought I have in my box a bunch of 74xx chips and could use an OR or NOR gate from one of those but don't really want the bother of adding additional hardware and wiring if I can help it. Many thanks in advance. Terry
