Hello All,
I have a circuit where I use jumpers to short traces (either trace 1 to trace 3 or trace 2 to trace 3). There is no power or ground involved here. To be specific I am connecting outputs from a 74HC4040 (Q8 or Q9) to reset pin of 74HC14 (MR). At present I have two jumpers each connected to Q8 and Q9 and the other ends of the jumpers to MR of 74HC14. At any given time I keep only one shorted using a jumper. Now I would like to replace that manual jumper setting with an electronic switch which I can control form a PC from my application.
Iniitally my idea was to use a small relay (SPDT), but then thought of using transistors too, but not exactly clear on how to use in my scenario.
Any ideas or suggestions are greatly appreciated.
thanks
