    Dear FvM and Waiyung

    I had found max2plus library.

    I need only one JK flip flop but i found a_7476 component has two flip flop.

    Could you show me which component has 1 JK flip flop?

    Thank you so much.

    You can use only one of the two. Leave the other one unconnected.

    Besides 7476, there's also a generic JK-Flip-Flop in the maxplus2 library

    component jkff
      port (	J  :  in STD_LOGIC;
        K  :  in STD_LOGIC;
        CLK:  in STD_LOGIC;
        CLRN: in STD_LOGIC;
        PRN:  in STD_LOGIC;
        Q  :  out STD_LOGIC);
    end component;
