Kagagami I would probably need to contemplate it for quite some time to fully grasp it. I had a sync. Any way, take into account that the SNN has been obsolete for 25 years, its not a good idea to even consider that part for a new design. MCU, comms module and voltage regulation sections.

Mikakasa 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. On top of that, when I will get into power-optimization for the MCU I may end up having to choose between keeping the interrupts alive or saving power. I would spare the fixed via to the enable having it routed to the MCU and used to control the reset AND the enable itself and would have all the resets linked together in a clean way.

Tony EE rocketscientist A state change on the inputs would wake the MCU — whereupon it reads the inputs and then goes back to sleep.

Why does this work? The most complex part by design is planned to be the Cf Any way, take into account that the SNN has been obsolete for 25 years, its not a datasheeg idea to even consider that part for a new design. Never say you are nobody! Thank you all for your help! Sign up using Facebook. I am working on a circuit where Datasbeet need to hold a few signals until my MCU reads them.

Thanks for the reply. Any suggestion on how to implement this otherwise? PDF CD Datasheet download 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 to toast stuff. But you all know how it works Historical anecdotes on my cd uses for RS latches.

SNN simply has all of its reset inputs internally connected. The shortcoming is that I have 4 separate resets, while ideally I would need only one. For this to work you need a pull-down resistor on cx output. If you look at the truth table of CD You can derive a similar deduction for CD Following up my previous comment: Looks like an SR is my only choice here, but my brain is just a drop of the ocean. You may be looking cdd this: I have toyed briefly with the possibility to use the Enable daatasheet, but was not sure if it would have cleared the latched states.

So you may then want to eatasheet another alternative. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I would disagree, but I may be missing the picture here. I want to keep it flexible, both capability and dagasheet wise and this requires balance. MCU, comms module and voltage regulation sections.

Thank you all for your help! However the doubt stand. Home Questions Tags Users Unanswered. You will then need pull-ups on every output instead of pull-downs, so just use the pull-ups of the MCU inputs by configuring it accordingly.
