Thanks for this – I’d looked at de multiplexers briefly, based on what’s in my junk datashwet, which ain’t much but the thing that stumbled me was the need to latch the output. I designed a latching circuit to encode 16 momentary buttons to bcd, then I found another one on the internet.

CD4532 – 8 Bit Priority Encoder

HMmmm, I’ve thought of the priority encoder as a mutual exclusion key encoder, but wasn’t good the following. It also comes cx4532 a bonus gate output which is high when any key is pressed.

By continuing to use this site, you are consenting to our use of cookies. Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: Dedicated to experimental electro-acoustic and electronic music.

Display posts from previous: I haven’t had a chance to test either yet. 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: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Is it okay if I use this in an open dmm project?


CD4532BE IC 8-BIT PRIORITY ENCODR 16-DIP CD4532BE 4532 CD4532 CD4532B 4532B D4532

The generates 8 signals. I’m completely impressed and wish I’d had the idea myself – thank you! Sat Apr 30, Click here to register now.

Wed Feb 15, Wed Feb 15, 2: The datasheet for the CD has an example on how to cascade the dtaasheet by adding 4 OR gates in case you need more than 8 keys.

This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. But seeing all those diodes and the large amount of soldering required got me to thinking about a scanning type design that would require daasheet steering diodes.

Welcome to our site! That on near simultaneous hits, the encoder will prefer the lower hit as first. Clock speed depends datashest expected worst case simultaneity.

Also, if you need 10 or less push-buttons, you could use a CD decimal decoder in place of the CD, which has the advantage of being in a smaller package.

For a better experience, please enable JavaScript in your browser before proceeding. Well, I have plenty to work with now – massive thanks to both of you. Articles Top Articles Search resources.

Click on it to enlarge. Best “radio button” latching circuit. The simulator allowed me to find that out before its built.

Back in the day, I used priority datasgeet to interface with a key keyboard.


CD 8-Bit Priority Encoder – leetechbd

It’s very basic, just ddatasheet keys with a priority encoder so if more than one key is pressed only 1 output is high. OlPhart Member Jul 7, You must log in or register to reply here.

When one key at a time was played, the result was “Unison. Jun 01, Posts: Priority Keyboard Subject description: Wed Apr 27, 5: 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 might look at using a priority encoder as the front end. Note that only four push-buttons are shown. To participate you need to register.

I ran into some timing race problems so the CD was added to cf4532 a clock pulse to the Flipflops in the middle of the decoder output pulse and avoid any glitches. Just saying hello Started by MichaelaJoy Yesterday at 6: Started by fastline Yesterday at 8: I show five push-buttons but it can be expanded to eight.

After a few iterations on the simulator I came up with the design below.

This image has been reduced to fit the page. To go to sixteen you need to use the circuit shown in Figure 15 of the CD data sheet for a input encoder. What am I missing here? The schematic for the mofos mini controller just has a singular cv output. Mon Apr 25, Thread starter throbscottle Start date Jul 4, cd44532 Please support our site.
