    Hi, just learning Multisim,

    I'm looking to place a D-type flip-flop with a positive-edge trigger in multisim. An internet search tells me that the part number for this is 74HC74D.

    I add this number in Multisim and there is a circle on the 1clk pin. My lecturer tells me this means it is a negative edge trigger. Is he right and if so what is the correct IC number for the component I wish to add? Or can I change this in the component properties?

    Thanks in Advance
