I just drew this up as part of a bigger circuit but it might come dstasheet handy for a lunetta controller. Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: Click Image to view fullscreen.

HMmmm, I’ve thought of the priority encoder as a mutual exclusion key encoder, but wasn’t good the following. Mon Apr 25, Welcome to our site!

CD4532 – 8 Bit Priority Encoder

After a few iterations on the simulator I came up with the design below. You could also replace the switches with some digital inputs, hook up a bunch of oscillators and have it play by itself, this is afterall the lunetta section. You need to expand that to the number of push-buttons you want.


Wed Feb 15, 2: But seeing all those diodes and the large amount of soldering required got me to thinking about a scanning type design that would require no steering diodes. I show five push-buttons but it can be expanded to eight.

Is datasheeet okay if I use this in an open dmm project? Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Please support our site. Also, if you need 10 or less push-buttons, you could use a CD decimal eatasheet in place of the CD, which has the advantage of being in a smaller package. Thread starter throbscottle Start date Jul 4, You might look at using a priority encoder as the front end.

CD – 8 Bit Priority Encoder

OlPhart Member Jul 7, I used TTL, though. Well, I have plenty to work with now – massive thanks to both of you. That on near simultaneous hits, the encoder will prefer the lower hit as first.

Jun 01, Posts: Parts to look at include: The datasheet for the CD has an example on how to cascade the chips by adding 4 OR gates in case you need more than 8 keys.

Clock speed depends on expected worst case simultaneity. Are these summed together to make a CV signal?

Just saying hello Started by MichaelaJoy Yesterday at 6: Ok, I had to try the priority encoder circuit also. This image has been reduced to fit the page. By continuing to use this site, you are consenting to our use of cookies.

Datashwet “radio button” latching circuit. Potentiometer Questions Started by norbss Yesterday at Started by fastline Yesterday at 8: Moon Base Audio files: My version uses R-S flip-flops, creating a small delay to set each flip-flop after they have all been reset component values are fairly arbitrary at this stage and I haven’t given it a “zero” button, and missed out the switch symbols since LTSpice doesn’t have one The AND gate version I found latches using positive feedback, and is from here: Back in the day, I used priority encoders to interface with a key keyboard.

Note that only four push-buttons are shown.
