Datqsheet to Binary [closed] Ask Question. The circuit with 6 ICs does convert all 3 digit BCD numbers to a correct result with 10 binary bits.

The purpose of the many binary datasjeet BCD converter ICs that are around are to support 7-segment displays in the pre-cheap-microcontroller era. You’ll need 6 for converting 0 to If you go on eBay, you can get 20 year old Russian knockoffs for a couple of bucks apiece.

Without knowing much more about the problem you are trying to solve, your best bet is to use a cheap microcontroller. See the How to Ask page for help clarifying this question.


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 extra protection logic is necessary only if the result should be represented with 8 bits 0 to only. For a complete 3 digits BCD to binary converter you need 10 output bits for numbers from 0 to Dec 21 ’17 at Where are the 3 digits coming from?

As has been pointed out in other answers, you can use the venerable and I do mean venerable Jon 3, 7 Home Questions Tags Users Unanswered. This comes in a 28 pin DIP, and they are readily available and easily programmed.

The reason for this is that there is no common reason for a BCD to binary converter. Uwe 3 5.

Of course, those things have been obsolete for decades, so finding them is You could also make something using discrete logic, which would be a good learning exercise, but will quickly become dataeheet reasonably complicated project in itself. 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.


Please clarify your specific problem or add additional details to highlight exactly what you need. Besides, your question is really underspecified and smells like an XY problem from miles away.

If this question can be reworded to fit the rules in the help centerplease edit the question. Or you do a single chip solution using a PROM with 12 inputs and 10 outputs.

Where do the BCD digits come from that you need to convert? Thumb wheels cheap from China? Of course you may use a PROM with 8 inputs and 8 outputs too. Then, of course, your 6 ICs will draw worst case as much as mA each, so you’re looking at mA. WhatRoughBeast 49k 2 28 Without an MCU, it’s going to quickly be a mess of logic chips and wires, if you need more than two digits Yes, dattasheet struggle to find one.

Overall, in terms of circuit board size, power dissipation and error resistance, you’re much better off programming a 4k x 8 PROM such as a As you can imagine, this was a rather common function in electronics devices, hence why the chips are readily available.
