You can derive a similar deduction for CD You matter to me! But I guess that the restrictions datasgeet far more If you look at the truth table of CD Given the available info, this is probably the correct answer. 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.

For this reason is important that the circuit is able to record a state change even if brief without any clock or external intervention. A state change on the inputs would wake the MCU – whereupon it reads the inputs and then goes back to sleep.

Tony EE rocketscientist I want to keep it flexible, both capability and power-usage wise and this requires balance. Sign up or log in Sign up using Google. Can’t yet wrap my head around applying a D or JK that way.



I had a sync. Home Questions Tags Users Unanswered. 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. Enric Blanco 4, 5 11 The shortcoming is that I have 4 separate resets, while ideally I would need only one. On processors such as the Atmel AVR that power is in the single daatsheet region – the clock doesn’t need to be cc4044. Looks like an SR is my only choice here, but my brain is just a drop of the ocean.

Look for “Wake-up on pin change”, not interrupt. EDIT dattasheet to clarify a few points in the design: MCU, comms module and voltage regulation sections.

The way I plan to implement it the MCU could well stay sleeping all the day, until the measurements are taken and the SR reset.

Sourcing it could be really troublesome. For this to work you need a pull-down resistor on every output.

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. Their later comment says the MCU would be sleeping, before you posted your ‘answer’.

Historical anecdotes on my other uses for RS latches. As has been said, you can make this function from more 74HCT-etc gates. While this is not a huge problem to solve and still match my requirements, the resulting design is not as clear cr4044 it would be with a single Reset and the density is lower, requiring me to use more ICs.

Any suggestion on how to implement this otherwise?

I think you need to re-evaluate how much power is required by “keeping the interrupts alive”. Path-wise, the design difference wouldn’t look enormous, but would still be an improvement: Is there a reason why you have to use the fewest ICs?
