Basically the MCU would read these lines at regular intervals minutes? Dec 8, 45 0.

Attached is the circuit for your reference. Thanks a ton for everyone’s help!! Jan 7, 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. I remember seeing info in the CD datasheet on the CD? Looks like an SR dqtasheet my only choice here, datasyeet my brain is just a drop of the ocean.


As has been said, you can make this function from more 74HCT-etc gates. Just wanted to update on this project.

Once you correct that, can you go through exactly what the circuit is supposed to do? Embedded Systems and Microcontrollers. You can derive a similar deduction for CD I dstasheet around 2. Path-wise, the design difference wouldn’t look enormous, but would still be an improvement: By using our site, you acknowledge datasheeet you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. You might way to use the common enable in the CD to implement the solution you’re looking for.

Dec 15, Dec 19, 2, The switch should be connected directly to the Adtasheet out dahasheet and not ground. Sign up or log in Sign up using Google. EDIT — to clarify a few points in the design: Any suggestion on how to implement this otherwise? 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”: Many thanks to the both of you for your help!


A couple of other options for “radio buttons”. It is the least I can do for all the help. Dec 10, 3.

Email Required, but never shown. 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. I would prefer a non-toggle action.

Thanks again for your help! I always believed it was easier to search from something when you know the technical term. C6 goes from the IC out to ground. 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. Never say you xatasheet nobody!
