I'm designing an arduino board to read inputs from HVAC devices on or off and logging on times. I would like to use an interrupt to read device status and not poll all 8 inputs all the time. Problem with this design now is if I get a second interrupt on the board output to interrupt pin will not see it. I would like to add something like a one shot IC to set interrupt when ever I get a change on any input. Would love some suggestions on this projects and maybe what IC I may need to add. Circuit is attached and I hope is readable

please help.
