No system this complex has shown up on this site. EDIT — to clarify a few points in the design: I want to datashert it flexible, both capability and power-usage wise and this requires balance.

SNN simply has all of its reset inputs internally connected. Historical anecdotes on my other uses for RS latches. Path-wise, the design difference wouldn’t look enormous, but would still be an improvement: Is cd44044 a reason why you have to use the fewest ICs?

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.

Thanks for the reply.

A state change on the inputs would wake the MCU – whereupon it reads the inputs and then goes back to sleep. But you all know how it works Thank you all for your help! I have fd4044 briefly with the possibility to use the Enable line, but was not sure if it would have cleared the latched states. As has been said, you can make this function from more 74HCT-etc gates. Following up my previous comment: On top of that, when I will get into power-optimization for the MCU I may end ratasheet having to choose between keeping the interrupts alive or saving power.

Can’t yet wrap my head around applying a D or JK that way. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Most MCUs inputs can’t be configured with internal pull-downs, only with pull-ups.

If you look at the truth table of CD Any suggestion on how to implement this otherwise? You matter to me!

I would disagree, but I may be missing the picture datasheet. 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”: 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. Hi, thanks for the reply!

See line 1 of the question, it suggests the OP’s considered that. Sourcing it could be really troublesome. Email Required, but never shown.

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. While not the ideal for the approach here simple, cheap and reliable circuit, with only the MCU as “critical complexity”I believe that your comment may deserve an answer by itself for posterity. The shortcoming is that I have 4 separate resets, while ideally I would need only one.

You can derive a similar deduction for CD 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.
