The clock signal from the astable causes the CD binary counter to continually cycle through its 16 states. Sat Apr 30, 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. Click on it to enlarge. Note that only four push-buttons are shown. To participate you need to register.

There shouldn’t be a race problem with the latch since the GS output delay is less than the decoded output delay and the latch latches on the falling edge of the clock [GS] input. You need to cs4532 that to the number of push-buttons you want.

CD – CD 8-Bit Priority Encoder

Thread starter throbscottle Start date Jul 4, I show five push-buttons but it can be expanded to eight. Dtasheet 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 dataasheet I haven’t given it a “zero” button, and missed out the switch symbols datxsheet LTSpice doesn’t have one The AND gate version I found latches using positive feedback, and is from here: Hi, I’ve been looking to make a dead simple CV keyboard with keys that are etched like those you see in remotes: It’s shown below with a CD encoder and a CD 4-bit latch.

CD4532 – 8 Bit Priority Encoder

Live streaming at radio. 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. 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.

Priority Keyboard Subject description: Forums New posts Search forums. You could add some pots to the outputs like a baby 10 to make it into an adjustable CV keyboard. Please support our site. What am I missing here?

CD4532 8-Bit Priority Encoder

Wed Apr 27, 5: Back in the day, I used priority encoders to interface with a key keyboard. Jan 14, Posts: The schematic for the mofos mini controller just has a singular cv output. 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.


Click here to register now. The 4-bit binary counter output goes to a CD 4-to decoder and to 4 D-Flipflops. Click Image to view fullscreen. Dedicated to experimental electro-acoustic and electronic music. After a few iterations on the simulator I came up with the design below. I haven’t had a chance to test either yet. When one key at a time was played, the result was “Unison. 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.

Wed Feb 15, 2: Well, I have plenty to work with now – massive thanks to both of you. View unread posts View new posts in the last week Mark the topic unread:: It also comes with a bonus gate output which is high when any key is pressed. They seem similar in parts and complexity so I can’t readily say which is best.

That on near simultaneous hits, the encoder will prefer the lower hit as first. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at
