Just like what the title said, is there a 1-bit full adder ic? I asked this since this professor of mine keep insisting that there is a 1-bit full adder but I already search all through out the internet and found nothing, my classmates even ask the local electronic shops in my area (btw, we are making a project but that professor insisted that we must use a 1-bit full adder ic).

If there is one, can anyone tell me what its name?

If there is none I'm planning to use a 2-bit full adder ic (even if there is a deduction in my grade). Is it the 74LS183? I already search this on the internet but I just want to make sure.

 

Hello,

Have a look at the SN7480.

Bertus

 

Since this is school work, finding the IC might be part of the problem.

The IC @bertus suggested is what I found in the Functional Index/Selection Guide in my 1976 TTL Data Book; in a matter of seconds.

 

Apparently, the 7480 (http://www.weisd.com/store2/NTE7480.pdf) and Signetics 8268 are 1-bit full adders.

You search all through the internet, huh?

Hmm.

There's this new tool that might help, though it's obscure, hard to find, and even harder to use:

But right there is the 7480.

I already saw that 7480 but the datasheets I see are from the 748X so I thought that's not it. And I'm trying to simulate it in multisim and there is no 7480

it looks like it is wrong to ask here, just ignore this post, gonna work it out myself.

 

If you had to pay for your version of Multisim, you should be able to create your own components.

Since this appears to be homework, we're not supposed to give answers; just guidance.

So which is it? You searched the entire internet and found nothing? Or you already found the 7480 and decided not to mention that you had already found a 1-bit full adder IC when you asked whether or not such an IC exists?

 

If your adder merely needs to produce the single-bit sum of two bits, you get four adders in a package. If it must also have carry in and/or carry out, I know of no modern 2-bit full adder IC - it just isn't something of much use for anything. There are common devices that can be used to implement a full adder with carry in and carry out in a single IC, but presumably that is not what your prof is referring to.

 

PSOC 4 maybe, you can build in its fabric pretty very diverse HW solutions,
like adders, using one or all of these facilities -

1) LUT
2) Verilog
3) GUI tool

The logic elements available are in attached catalog under digital section. These
you drag and drop onto schematic, then wire them up internally and to external
pins.

There is a low end $ 4 board that would get you started, tools are free.

Regards, Dana.

 

PSOC 4 is almost certainly not an option available to the TS for this homework assignment, for which it appears they are expected to use Multisim.

 

The TS talks about seeking HW so I interpreted this to be both sim followed by
proto ?

What is there about this that you don't understand?

(btw, we are making a project but that professor insisted that we must use a 1-bit full adder ic).

 

Also, checkout SN74H183 or SN74LS183. This is two single adders in one DIP. Is what you really want the logic circuit from the old data books or the actual part? If just the logic diagram, search images on the net for the part. Voila!

 

Given that the assignment was from a year ago, it's a pretty safe bet that the TS isn't still trying to find solutions to this problem.

I hate it when I go through a time warp.
