Electronic – How to find the schematic diagram of a component in Multisim

integrated-circuitmultisim

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.
