When it comes to this IC stuff, I have absulutely no experience in this stuff but I always like to learn. Since it is regulated and is what the rest of the components run off, I was going to use the 3. Enric Blanco 4, 5 11 OTOH, you might way to use the common enable in the CD to implement the solution you’re looking for. Dec 10, 3.

However the doubt stand. Looks like an SR is my only choice here, but my brain is just a drop of the ocean. Dec 11, 6. As has been said, you can make this function from more 74HCT-etc gates.

LED selection indicators controlled by multiple switches

Dec 10, 5. There’s a good chance that quiescent current added to the system by an extra logic IC would be greater than the current datxsheet by the MCU waking up and executing a handful of instructions.


Email Required, but never shown.

Dec 10, 2. Is the enable line capable of effectively “resetting” the latches? On top of that, when Datashset will get into power-optimization for the MCU I may end up having to choose between keeping the interrupts alive or saving power.

I would prefer a non-toggle action. Dec 16, SNN simply has all of its reset inputs internally connected. The CD is indeed the one I have in the design now. Dec 10, 4.

No system this complex has shown up on this site. It is the least I can do for all the help. Thanks again for your help! Basically just have a short signal to trigger the reset instead of a continuous high signal as would be from the Vd4043 output. MCU, comms module and voltage regulation sections. I see how you are using the output of IC1A to reset the others and diodes to control signal flow.

A state change on the inputs datashert wake the MCU – whereupon it reads the inputs and then goes back to sleep. The most complex part by design is planned to be the MCU.

The main use is for channel switching I say main becuase when the amp is in manual mode, the buttons control other things but this mod is for channel indicators It is connected via a TRS plug basic 3-connductor stereo plug S1 switch is for changing the bank Red or Green LED and the CH is for the different channels the amp can store 4 channels per each of the two banks Changes the voltage of the signal line S 3.


I think I will have to stick with that option for now. Please note I’ve never tested it, yet I think it will work. You matter to me! ON part of the switch is not used but has Vo I could split the poles having 2 isolated switches and connect per original idea. Dec 17, I want to keep it flexible, both capability and power-usage wise and this requires balance. Sourcing it could be really troublesome.

I had no clue the other way wouldn’t work. Can’t yet wrap my head around applying a D or JK that way. If you look at the truth table of CD Embedded Ratasheet and Microcontrollers. I thought the IC could handle 10mA. Given the available info, this is probably the correct answer.
