How to find the schematic diagram of a component in Multisim?
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.
