Could someone please tell me how to find the schematic diagram of a given conponent in Multisim, I've been trying to understand how does the IC 74LS729 (SR latch) work but coudn't succeed mostly because this component doesn't behave like a normal SR latch would and it also includes another input called S3 whose function is also unclear to me.

Any help would be more than welcomeenter image description here

It probably works quite a bit like a 74LS279A.

There are two different types of latches inthe '279A. Out of the 4 latches, 2 have just one \$\bar{S}\$ input, and 2 have dual \$\bar{S}\$ inputs. The Multisim component appears to have just one of each of these types instead of two of each.

If you mean the 74LS279N (as opposed to the 74LS729 you mention in the text), you can look at the datasheet for the connection diagram.

Look at the actual pin numbers in the datasheet, rather than the names. It should make sense after that.
