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. Is it okay if I use this in an open dmm project? Note that only four push-buttons are shown. 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.

It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high.

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: Click on it to enlarge.

It’s shown below with a CD encoder and a CD 4-bit latch.

CD4532 – CD4532 8-Bit Priority Encoder

View unread posts View new posts in the last week Mark the topic unread:: 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. Ok, I had to try the priority encoder circuit also. Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: Started by fastline Yesterday at 8: Wed Feb 15, 2: Sep 05, Posts: Priority Keyboard Subject description: Just saying hello Started by MichaelaJoy Yesterday at 6: Sat Apr 30, OlPhart Member Jul 7, I didn’t have a model for that in my simulator Electronic Workbench so had to use the CD for the simulations.

I designed a latching circuit to encode 16 momentary buttons to bcd, then I found another one on the internet. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at 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.

Please support our site. Dedicated to datashewt electro-acoustic and electronic music. To go to sixteen you need to use the circuit shown in Figure 15 of the CD data sheet for a input encoder.

Display posts from datassheet Even better but credit where it’s due, it was ChrisP58’s idea to use a priority encoder, not mine! I show five push-buttons but it can be expanded to eight. 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.

I’m completely impressed cd45332 wish I’d had the idea myself – thank you! Thread starter throbscottle Cd4523 date Jul 4, Back in the day, I used priority encoders to interface with a key keyboard. Welcome to our site!
