Any suggestion on how to implement this otherwise? As has been said, you can make this function from more 74HCT-etc gates.
Dec 10, 3. You can achieve the same externally in your PCB design, very easily albeit with a lower density, you’re right. I have toyed briefly with the possibility to use the Enable line, but was not sure if it would have cleared the latched states. 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.
Yes, my password is: Your name or email address: You can test it using a breadboard. Dec 10, 4.

On top of that, when I 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 disagree, but I may be missing the picture here.
Do you already have an account? 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 resets linked together in a clean way. Quote of the day.

Dec 15, I can seem to find specifics on that. Tony EE rocketscientist LED selection indicators controlled by multiple switches Reply to Thread. Got some parts in today to test and a new solderless breadboard I have wanted to get one for years. Always ratasheet one LED on. Thanks for your input!
But I guess that the restrictions were far vatasheet One thing I did find is that with 3. Jan 7, R3 was moved to the right just to clear up some clutter. Led light controlled by dmx Posted by charles01 in forum: Jan 4, 65 2.
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.

Historical anecdotes on my other uses for RS latches. Please note I’ve never tested it, yet I think it will work.
Look for “Wake-up on pin change”, not interrupt. You may be looking for this: Thanks for the reply. I’ll do a little testing to measure current draw and should be ready for the perfboard. I will have to look at these shematics some more later.
