Please clarify your specific datashwet or add additional details to highlight exactly what you need. Then, of course, your 6 ICs will draw worst case as much as mA each, so you’re looking at mA. Thumb wheels cheap from China?

The extra protection logic is necessary only if the result should be represented with 8 bits 0 to only. Without knowing much more about the datashert you are trying to solve, your best bet is to use a cheap microcontroller.

Of course you may use a PROM dqtasheet 8 inputs and 8 outputs too. You could also make something using discrete logic, which would be a good learning exercise, but will quickly become a reasonably complicated project in itself. Where are the 3 digits coming from?

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. For a complete 3 digits BCD to binary converter you need 10 output bits for numbers from 0 to You’ll need 6 for converting 0 to Yes, you’ll struggle to find one. Daatsheet 49k 2 28 Where do the BCD digits come from that you need to convert?

Decimal to Binary [closed] Ask Question.

If you go on eBay, you can get 20 year old Russian knockoffs for a couple of bucks apiece. 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.

The reason for this is that there is no common reason for a BCD to binary converter. Without an MCU, it’s going to quickly be a mess of logic chips and wires, if you need more than two digits Or you do a single chip solution using a PROM with 12 inputs and 10 outputs. 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.

Of course, those things have been obsolete for decades, so finding them is Jon 3, 7 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 circuit with 6 ICs does convert all 3 digit BCD numbers to a correct result with 10 binary bits. Dec 21 ’17 at On page 6 or there is a cascaded circuit using 6 chips for 3 BCD digits input and 10 binary output bits.

Besides, datazheet question is really underspecified and smells like an XY problem from miles away. This comes in a 28 pin DIP, and they are readily available and easily programmed. Uwe 3 5.
