Dec 10, 2. Sign up or log in Sign up using Google. Given the available info, this is probably the correct answer. Got some parts in today to test and a new solderless breadboard I have wanted to get one for years. Yes, my password is: You guys are the experts here! Following up my previous comment: Path-wise, the design difference wouldn’t look enormous, but datsaheet still be an improvement: I thought the IC could handle 10mA.
Thank you all dataheet your help! Jan 7, LED Indicators Posted by opalloyd in forum: I will let you know how it turns out once I can get someone to test it.

Dec 15, 8. Dec 8, 1. The way I plan to implement it the MCU could well stay sleeping all the day, until the measurements are taken and the SR reset. There’s a good chance that quiescent current added to the system by an extra logic IC would be greater than the current consumed by the MCU waking up and executing a handful of instructions.
Historical anecdotes on my other uses for RS latches. Don’t worry about the mistake.

Dec 15, A state change on the inputs would wake the MCU – whereupon it reads the inputs and then goes back to sleep. Most MCUs inputs can’t be configured with internal pull-downs, only with pull-ups.
But I guess that the restrictions were far more For this reason is important that the circuit is able to record a state change even if brief without any clock or external intervention.
I would prefer a non-toggle action. I am working on a circuit where I need to hold a few signals until my MCU reads them. MCU, comms module and voltage regulation sections.
I’ll do a little testing to measure current draw and should be ready for the perfboard. Never say you are nobody! Comments like these are one of the many reasons for which I regret skipping all the theory in the electronic classes and being in the first line only when there was the risk datashewt toast stuff. I always believed it was easier to search from something when you know the technical term.
I have toyed briefly with the possibility to use the Enable dxtasheet, but was not sure if it would have cleared the latched states.
Tony EE rocketscientist Thanks a ton for everyone’s help!!
Their later comment says the MCU would be sleeping, before you posted your ‘answer’.
