Sep 26, 8. I don’t get it.

No, create an account now. Thanks, actually I did think of that solution being a possibility. And that’s not really the output I want. This is what I want: Your name or email 74hc18 I’m also controlling the 3-bit signal from a micro controller so any changes to the bit-combination is also possible.

Help needed: Alter simple circuit with 74HC138

If it’s enabled 74ch138 E1-E3, just one output bit can be active. See what inverting the address bits does for you. Or have 8 independent outputs from the processor, if they’re available. I really appreciate your help.

74ch138 verified that I have access to theand I’ve looked at the ‘s datasheet but can’t see how I’m suppose to implement it. What will the circuit look like and how does the input values match the output on the LEDs?

Sep 25, 5. Photon Wrangling with Nano-Antennae Good news for those looking forward to quantum computing. Someone told me I should look into using multiple 74jc138 to produce the outcome but it doesn’t seem obvious to me at this point How can I get the output I want using a minimal amount of components?

Hi there, I’ve just begun studying digital electronics, and I have to do a small project.

Take another look at the truth table. A team of physicists from the Hebrew University of Jerusalem in Israel have developed a single photon source that is not only compact, but also operates at ambient temperatures.

If using a 74HC driven by a microcontroller is a possibility–then yes, do it that way. I don’t see how the can ever do this job. Help With Simple Circuit Posted by tim. 74hc18 24, 3.

Yes, I can’t alter the number of LEDs. Sep 25, 7. There are at leastresults, some with detailed descriptions and circuit diagram. I think I’ll use that approach to begin with and see how it goes Thanks again! Do you already have an account?

And I guess it would be the simplest way of dealing with this. Help needed with a simple radio circuit Posted by AlwaysNumber1 in forum: Strides Towards Quantum Computing:
