Any way, take into account that the SNN has been obsolete for 25 years, its not a good idea to datasheeh consider that part for a new design. Why does this work? Looks like an SR is my only choice here, but my brain is just a drop of the ocean.

Eatasheet this is not a huge problem to solve and still match my requirements, the resulting design is not as clear as it would be with a single Reset and the density is lower, requiring me to use more ICs. So you may then want to consider another alternative. The CD is indeed the one I have in the design now. No system this complex has shown up on this site.

A state change on the inputs would wake the MCU – whereupon it reads the inputs and then goes back to sleep. Enric Blanco 4, 5 11 Post as a guest Name.

I want to keep it flexible, both capability and power-usage wise and this requires balance. Email Required, but never shown. Home Questions Tags Users Unanswered. The shortcoming is that I have 4 separate resets, while ideally I would need only one.

Never say you are nobody! I am working on a circuit where I need to hold a few signals until my MCU reads them. I think you need to re-evaluate how much power is required by “keeping the interrupts alive”.

Their later comment says the MCU would be sleeping, before you posted your ‘answer’.

Comments datssheet 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.

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.

As far as possible I want to keep it digital and without any high frequency line anywhere or, better said, well confined in their own “realm”: I had a sync.

However is practically impossible to find good supply of it and even a datasheet. The reason why I was looking at concentrating everything in Hex Latches instead of Quad Latches was to reduce the IC count and, with this, to have a cleaner design of the traces. However the doubt stand. Path-wise, the design difference wouldn’t look enormous, but would still be an improvement: I would disagree, but I may be missing the picture here.

SNN simply has all of its reset inputs internally connected. Thank you all for your help! For this reason is important that the circuit is able to record a state change even if brief without any clock or external intervention.
