CD4532 8-Bit Priority Encoder
Moon Base Audio files: Sep 05, Posts: Ok, I had to try the priority encoder circuit also.
The generates 8 signals. Replacing a 4 pin leaded inductor with a 2 pin Started by cs4532 Yesterday at Articles Top Articles Search resources. 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.
Live streaming at radio. I haven’t had a chance to test either yet. Datashret seem similar in parts and complexity so I can’t readily say which is best.
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.

Please support our site. Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: 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: Note that only four push-buttons are shown.
This image has been reduced to fit the page. 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. I just drew this up as part of a bigger circuit but it might come in handy for a lunetta controller.

Click datsaheet it to enlarge. Best “radio button” latching circuit. It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high. Clock speed depends on expected worst case simultaneity. View unread posts View new posts in the last week Mark the topic unread:: You might look at using a priority encoder as the front end.
datashfet Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Is it okay if I use this in an open dmm project? 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.

It also comes with a bonus gate output which is high when any key is pressed. If you click through and buy from our affiliate partnerswe earn a small commission.
