However is practically impossible to find good supply of it and even a datasheet. Thanks a ton for everyone’s help!!

Path-wise, the design difference wouldn’t look enormous, but would still be an improvement: Do you already have an account?

I would disagree, but I may be missing the picture here. 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.

Looked at quad switch ICs but those seem to be like independent switches where you can have more than one on at a time. I might stick with the because it uses only one IC chip. R3 was moved to the right just to clear up some clutter. Just out of curiosity, would it be possible to do the same thing by running that reset signal from the SW1 instead of Datsheet 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.


Basically the MCU would read these lines at regular intervals minutes?

LED selection indicators controlled by multiple switches

You guys are the experts here! Basically just have a short signal to trigger the reset instead of a continuous high signal as would be from the LED output. 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 dattasheet a handful of instructions. To conserve xd4043, 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 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 xd4043 linked together in a clean way. Jan 4, 65 2. Embedded Systems and Microcontrollers. For this to work you need a pull-down resistor on every output. 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.

The shortcoming is that I have 4 separate resets, while ideally I would need only one.


A couple of other options for “radio buttons”. OTOH, you might way to use the vd4043 enable in the CD to implement the solution you’re looking for. Their later comment says the MCU would be sleeping, before you posted your ‘answer’. But you all know how it works Sign up or log in Sign up using Google.

The most complex part by design is planned to be the MCU.

Happened on this board while searching the internet with no luck. Sourcing it could be really troublesome. I had no clue the other way wouldn’t work. Any help is appreciated. I would probably need to contemplate it for quite some time to fully grasp it.

Email Required, but never shown. When it comes to this IC stuff, I have absulutely no experience in this stuff but I always like to learn. I’m still trying to get used to those truth tables.
