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 dataxheet section.
Intersil Corp. CD Datasheet.
Please support our site. They seem similar in parts and complexity so I can’t readily say which is best. Just saying hello Started by MichaelaJoy Yesterday at 6: Dstasheet, I have plenty to work with now – massive thanks to cv4532 of you.
You might look at using a priority encoder as the front end. Started by fastline Yesterday at 8: To participate you need to register. You must log in or register to reply here.
CD 8-Bit Priority Encoder – Senith Electronics
Dedicated to experimental 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. 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: I’m completely impressed and wish I’d had the idea myself – thank you!
Parts to look at include: 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.

Click on it to enlarge. 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.
CD4532BE IC 8-BIT PRIORITY ENCODR 16-DIP CD4532BE 4532 CD4532 CD4532B 4532B D4532
The generates 8 signals. Clock speed depends on expected worst case simultaneity. It’s very basic, just 8 keys with a priority encoder so if more than one key is pressed only 1 output is high. I designed a latching circuit to encode 16 momentary buttons to bcd, then I found another one on the internet. Sep 05, Posts: That on near simultaneous hits, the encoder will prefer the lower hit as first.
CD4532 – CD4532 8-Bit Priority Encoder
So take your pick.
Is it okay if I use this in an open eatasheet project? After a few iterations on the simulator I came up with the design below. The clock signal from the astable causes the CD binary counter to continually cycle through its 16 states. Forums New posts Search forums. But seeing all those diodes and the large amount of soldering required got me to thinking about a scanning type design that would dayasheet no steering diodes.
Ok, I had to try the priority encoder circuit also. Display posts from previous: I haven’t had a chance to test either yet. The simulator allowed me to find that out before its built. Note that only four push-buttons are shown. Click here to register now. Electro Dtaasheet is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
Welcome to our site! Click Image to view fullscreen. I show five push-buttons but it can be expanded to eight. I used TTL, though.
Potentiometer Questions Started by norbss Yesterday at I just drew this up as part of a bigger circuit but it might come in handy for a lunetta controller. Back in the day, I used priority encoders to interface with a key keyboard.
