I thought the IC could handle 10mA. Quote of the day. Email Required, but never shown. I think I will have to stick with that option for now. Actually, the second one is pretty much the same as tkng’s. You can test it using a breadboard. I think you need to re-evaluate how much power is required by “keeping the interrupts alive”.

Basically just have a short signal to trigger the reset instead of a continuous high signal as would be from the LED output. Dec 15, You can achieve the same externally in your PCB design, very easily albeit with a lower density, you’re right.

When it comes to this IC stuff, I have absulutely no experience in this stuff but I always like to learn. Look for “Wake-up on pin change”, not interrupt. Sign up using Email and Password. Dec 8, 1. Thanks again for your help! Dec 15, 9. You might way to use the common enable in the CD to implement the solution you’re looking for.

Historical anecdotes on my other uses for RS latches. Once you correct that, can you go through exactly what the circuit is supposed to do? So you may then want to consider another alternative. So moving those diodes and disconnecting the D and barQ will make satasheet pretty much the same as Ken’s diagram if I’m not mistaken aside from the output transistors. One thing I did find is that with 3. Dec 8, 45 0.

Dec 10, 5. Embedded Systems and Microcontrollers. I want to keep it flexible, both capability and power-usage wise and this requires balance. Tony EE rocketscientist Enric Blanco 4, 5 11 I have toyed briefly with the possibility to use the Enable line, but was not sure if it would have cleared the latched states. No system this complex has shown up on this site.

Given the available info, this is probably the correct answer. LED selection indicators controlled by multiple switches Reply to Thread. I see a small error from moving parts around.

Dec 11, 7. I will fix that tonight. I might stick with the because it uses only one IC chip.

No, create an account now. Don’t worry about the mistake. I had no clue the other way wouldn’t work. The shortcoming is that I have 4 separate resets, while ideally I would need only one.

I am working on a circuit where I need to hold a few signals until my MCU reads them. Sourcing it could be really troublesome.

Hi, thanks for the reply! Thanks a ton for everyone’s help!! However is practically impossible to find good supply of it and even a datasheet. LED Indicators Posted by opalloyd in forum: Their later comment says the MCU would be sleeping, before you posted your ‘answer’.

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. I’m still trying to get used to those truth tables. OTOH, you might way to use the common enable in the CD to implement the solution you’re looking for.
