There’s a good chance that quiescent current added to the system by an extra logic IC would be datasheer than the current consumed by the MCU waking up and executing a handful of instructions.
Yeah, looked at the D and JK logic, but that would require providing clock and wouldn’t be an “unattended” design as I plan to implement. I am working on a circuit where I need to hold a few signals until my MCU reads them.
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. You matter to me!

For this to work you need a pull-down resistor on every output. 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.
Thanks for the reply. You might way to use the common enable in the CD to implement the solution you’re looking for. On processors such as the Atmel AVR that power is in the single microamp region – the clock doesn’t need to be running.
Zio Stampella 8 3. SNN simply has all of its reset inputs internally connected.

I would disagree, but I may be missing the picture here. Thank you all for your help!
As far as possible I want to keep it digital ccd4044 without any high frequency line anywhere or, better said, well confined in their own “realm”: Sign up or log in Sign up using Google. Can’t yet wrap my head dataaheet applying a D or JK that way. I had a sync. 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. Their later comment says the MCU would be sleeping, before you posted your ‘answer’.
Hi, thanks for the reply! While this is not a huge problem to solve and datxsheet 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.
No system this complex has shown up on this site. So you may then want to consider another alternative.

Given the available info, this is probably the correct answer. Enric Blanco 4, 5 11 For this reason is important that the circuit is able to record a state change even if brief without any clock or external intervention. However is practically impossible to find good supply of it and even a datasheet. Basically the Datasheet would cd40444 these lines at regular intervals minutes? But I guess that the restrictions were far more In cd40044 scenario a common reset channel on the IC would help maximizing the numbers of available latches in the same footprint and make the circuit more elegant and simple.
To conserve bandwidth, I only needed 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 Facebook. I want to keep it flexible, both capability and power-usage wise and this requires balance.
