So I’ve been looking all over the internet for a Decimal to Binary converter but all I’ve been able to find are Binary to Decimal converters, and Decimal to BCD circuits, does anyone have one? The purpose of the many binary to BCD converter ICs that are around are to support 7-segment displays in the pre-cheap-microcontroller era. Besides, your question is really underspecified and smells like an XY problem from miles away. WhatRoughBeast 49k 2 28 The reason for this is that there is no common reason for a BCD to binary converter.
Overall, in terms of circuit board size, power dissipation and error resistance, you’re much better off datzsheet a 4k x 8 PROM such as a Without knowing much more about the problem you are trying to solve, your best bet is to use a cheap microcontroller.
Of course, those things have been obsolete for decades, so finding them is As has been pointed out in other answers, you can use the venerable and I do mean venerable You’ll also need some extra protection logic, since with a 3-digit input there is always the chance that you will inadvertently try to enter a number in excess ofand the results of that will not be pretty.
On page 6 or there is a cascaded circuit using 6 chips for 3 BCD digits input and 10 binary output bits. This comes in a 28 pin DIP, and they are readily available and easily programmed.

Thumb wheels cheap from China? Without an MCU, it’s going to quickly be a mess of logic chips and wires, if you need more than two digits Of course you may use a PROM with 8 inputs and 8 outputs too.
Jon 3, 7 If you go on eBay, you can get 20 year old Russian knockoffs for a couple of bucks apiece.
Sorry, Anti-Hsp60 antibody [LK1], prediluted (ab74184) is not available
The extra protection logic is necessary only if the result should be represented with 8 bits 0 to only. You’ll need 6 for converting 0 to For a complete 3 digits BCD to binary converter you need 10 output bits for numbers from 0 dxtasheet Decimal to Binary [closed] Ask Question. See the How to Ask page for help clarifying this question.
Dec 21 ’17 at Where are the 3 digits coming from? Home Questions Tags Users Unanswered.
The datasneet with 6 ICs does convert all 3 digit BCD numbers to a correct result with 10 binary bits. Uwe 3 5. Yes, you’ll struggle to find one. As you can imagine, this was a rather common function in electronics devices, hence why the chips are readily available.

Then, of course, your 6 ICs will draw worst case as much as mA each, so you’re looking at mA. If this question can be reworded to fit the rules in the help centerplease edit the question.
7414 you do a single chip solution using a PROM with 12 inputs and 10 outputs.
You could also make something using discrete logic, which would be a good learning exercise, but 7184 quickly become a reasonably complicated project in itself.
