Hi group,
I need to create an interrupt on a state change of a GPIO pin. I'm thinking something like the attached circuit but I don't know which IC to use. I don't want to use a Micro CPU. The circuit will use an XOR IC to detect a change of state, then trigger the Sync pulse and store the new state.
I need to monitor 8 GPIO pins.
Any ideas?
Thanks for your time.

Will this work?
