Historical anecdotes on my other uses for RS latches. Sign up using Facebook. MCU, comms module and voltage regulation sections. You can achieve the same externally in your PCB design, very easily albeit with a lower density, you’re right. SNN simply has all of its reset inputs internally connected. I want to keep it flexible, both capability and power-usage wise and this requires balance. Can’t yet wrap my head around applying a D or JK that way.
Is the enable line capable datashfet effectively “resetting” the latches?
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.
Datashfet for “Wake-up on pin change”, not interrupt. You matter to me!
I would disagree, but I may be missing the picture here. To conserve bandwidth, I only daasheet 1 bit in a synchronous “sub-frame” channel to send the analog signal as a digital FM signal of 0 to 1kHz. Sign up using Email and Password. The most complex part by design is planned to be the MCU.
However the doubt stand. You can derive a similar deduction for CD 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.

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.
Zio Stampella 8 3. Why does this work? I think you need to re-evaluate how much power is daasheet by “keeping the interrupts alive”. I would probably need to contemplate it for quite some time to fully grasp it. Hi, thanks for the reply! Thanks for the reply.

I have toyed briefly with the possibility to use the Enable line, but was not sure if it would have cleared the latched states. Sourcing it could be really troublesome. Sign up or log in Sign up using Google.
Post as a guest Name. See line catasheet of the question, it suggests the OP’s considered that. Looks like an SR is my only choice xd4044, but my brain is just a drop of the ocean.
Email Required, but never shown. Backup question maybe deserving its own question: While 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. 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. 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.
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. However is practically impossible to find good supply of it and even a datasheet.
