2015年6月9日 · Hello, During the last classes we worked on 7447, 74185 converters and displaying DEC/BIN numbers. I`m stuck with my homework right now. Build a logical gate function ...

2013年1月8日 · Hello all, Can anyone tell me if theres an alternative to the 74185 binary to bcd converter or how I can make one? I cant find one anywhere in the UK.

2020年1月4日 · Hi, I try to design circuit that convert 10 bit binary to BCD with 74185 IC in Proteus, but when i run this project output of this IC like this attached picture is unknown(IC don't work!) and I did active enable. why? and how can give suitable output?

2019年8月15日 · 74185 is just a ROM. You can use an EPROM, programmed with an appropriate table, to replace it. Or you can design a circuit to do the conversion. One I designed took around 20 gates for 4 bits. Is this a school project?

2020年4月27日 · Welcome to AAC! Proteus can't simulate 74184 or 74185. That has been tried often enough by people posting on AAC that even us non-Proteus users are aware of the limitation. The workaround has been to use a programmable memory with the …

2007年3月28日 · The 74185 will do it but no! you can't get them and they pull about 50mA per device (TTL OLD HAT !!!). The job is done, and it works fine. it is a PCB about 50 x 55mm square and another about 50 x 25mm for the displays, it has on it 1 x 27C512 EPROM and 2 x 4511's, 14 resistors and a 100K x 8 in line resistor pack.

2023年12月30日 · The 74185 datasheet will give you some clues how to cascade logic that implements double dabble.

2018年11月28日 · Welcome to AAC! You're going to have to give us more information before we can help you. Does the fact that 74185 is unavailable affect your decision to use it? Is this homework? Binary to BCD conversion is a common homework question that few have solved because the ones who know how to do it don't come here for help...

2019年3月5日 · Hi, I am making a 32 bit binary calculator. With that I would like to display the answer on a few 7-segment displays. I can find schematics for such a converter but it requirs the sn74185a, which is badly availible. So do you have a alternitive ic or a schematic with logic gates? I …

2023年4月10日 · The 74185 ICs are quite expensive if you can find them! It may be a lot easier and cheaper to use an Arduino or Raspberry Pi Pico to drive an LCD or OLED display.
