Can’t yet wrap my head around applying a Datashete or JK that way. Is there a reason why you have to use the fewest ICs? As has been said, you can make this function from more 74HCT-etc gates.

You might way to use the common enable in the CD to implement the solution you’re looking for. Tony EE rocketscientist 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. I think you need to re-evaluate how much power is required by “keeping the interrupts alive”. Backup question maybe deserving its own question: 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. 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.

Never say you are nobody! 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.

However the doubt stand. 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.

So you may then want to consider another alternative. EDIT — to clarify a few points in the design: Path-wise, the design difference wouldn’t look enormous, but would still be an improvement: I am working on a circuit where I need to hold a few signals dtasheet my MCU reads them. I would disagree, but I may be missing the picture here.

Given the available info, this is probably the correct answer. Following up my previous comment: SNN simply has all of its reset inputs internally connected. But you all know how it works In this 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. The reason why Dafasheet 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.

Zio Stampella 8 3. On processors such as the Atmel AVR that power is in the single microamp region – the clock doesn’t need to be running. Enric Blanco 4, 5 11 If you look at the truth table of CD Looks like an SR is my only choice here, but my brain is just a drop of the ocean. Sign up using Email and Password. Is the enable line capable of effectively “resetting” the latches? You may be looking for this: The most complex part by design is planned to be the MCU.

Basically the MCU would read these lines at dwtasheet intervals minutes? Email Required, but never shown. 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”: You matter to me! Sourcing it could be cr4044 troublesome.

MCU, comms module and voltage regulation sections. The shortcoming is that I have 4 separate resets, while ideally I would need only one.
