Hello,
I need hold a logic state high, once achieved, until I intentionally change it, even if the initiating high reverts to low.
I'm using a CD4060 timer to put a circuit into low-power standby state. An idle circuit allows the timer to advance, and after about 20 minutes the Q14 pin goes high opening the power relay and de-energizing the power circuit (the standby/timer circuit retains power, of course). However, the timer will continue to advance indefinitely, and after another 20 minutes, Q14 will return to low and the power circuit will re-energize. I need to maintain the logic high initiated by Q14 until I intentionally change it.
At the moment, I'm considering a latching relay. Other thoughts/better ideas?
Thanks,
