(Datasheet) CDB pdf – CMOS 8-Bit Priority Encoder (1-page)

Please support our site. To participate you need to register. After a few iterations on the simulator I came up with the design below.

When a PB connected to the decoder output is depressed, the pulse from that output is used to latch the binary counter value of that PB position into the D-Flipflops. Click here to register now. The generates 8 signals. Question is, which is best? Click Image to view fullscreen. Priority Keyboard Subject description: View unread posts View new posts in the last week Mark the topic unread:: Thanks for this – I’d looked at de multiplexers briefly, based on what’s in my junk box, which ain’t much but the thing that stumbled me was the need to latch the output.

Even better but credit where it’s due, it was ChrisP58’s idea to use a priority encoder, not mine! For a better experience, please enable JavaScript in your browser before proceeding.

I just drew this up as part of a bigger circuit but it might come in handy for a lunetta controller.

Ccd4532 show five push-buttons but it can be expanded to eight. I ran into some timing race problems so the CD was added to give a clock pulse to the Flipflops in the middle of the decoder output pulse and avoid any glitches. The 4-bit binary counter output goes to a CD 4-to decoder and to cd4523 D-Flipflops.

Hi, I’ve been looking to make a dead simple CV keyboard with keys that datasueet etched like those you see in remotes: Thread starter throbscottle Start date Jul 4, Live streaming at radio. 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: Moon Base Audio files: Wed Apr 27, 5: Started by fastline Yesterday at 8: This image has been reduced to fit the page.

I designed a latching circuit to encode 16 momentary buttons to bcd, then I found another one on the internet. By continuing to use this site, c4532 are consenting to our use of cookies. OlPhart Member Jul 7, Just saying hello Started by MichaelaJoy Yesterday at 6: The clock signal cc4532 the astable causes the CD binary counter to continually cycle through its 16 states.

It also comes with a bonus gate output which is high when any key is pressed. To go to sixteen you need to use the circuit shown in Figure 15 of the CD data sheet for a input encoder. Potentiometer Questions Started by norbss Yesterday at It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high. Best “radio button” latching circuit. What am I missing datasbeet I didn’t have a model for that in my simulator Electronic Workbench so had to use the CD for the simulations.

Sat Apr 30, Parts to look at include: You might look at using a priority encoder as the front end. Jan 14, Posts: 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.

Well, I have plenty to work with now – massive thanks to both of you.

CD4532 – CD4532 8-Bit Priority Encoder

The schematic for the mofos mini datadheet just has a singular cv output. Mon Apr 25, You could add some pots to the outputs like a baby 10 to make it into an adjustable CV keyboard.

Ok, I had to try the priority encoder circuit also.
