Hi,

Probably, you may find the following resources useful

Getting started with Multisim

If you have a circuit designed in pspice you can design the same in Multisim too. Following tutorail may be of use.

Hi,

74ls75, 74ls08, 555 timer models are available in Multisim

For bc548 & ln4007 diode, you will need to create a custom componenet in Multisim. Please use the following tutorial
