flipflop.in 的奇怪行为

Question

为什么我在触发器的输入端看到这些奇怪的线

这就是应该做的

\begin{document}
\begin{tikz}
    \draw 
    (2,-.5) to[short] (2,-10)
    (0,0) to[short, -*] (1,0)
    (4,0) node[label,and port/] (myand1) {1}
    (1,-1) node[label,american not port,rotate=270] (prvone)    

    (1,0) -| (myand1.in 1)
    (2,-.5) -| (myand1.in 2)
    (1,0) -| (prvone.in)

     %node [american not port,rotate=270] (5,-3)    
    ;
\end{tikz}

\结束{文档}

这更符合你的要求吗？

\documentclass[border=10pt]{standalone}
\usepackage{circuitikz}

\begin{document}
\ctikzset{logic ports=ieee}
\begin{circuitikz}
    \draw 
    (0,0) to[short, -*] (1,0) -- (2,0) node[and port, anchor=in 1] (myand1) {1}
    (1,-1) node[american not port,rotate=-90] (prvone) {}
    (myand1.in 2) -| (2,-4)
    (1,0) -| (prvone.in)
    (myand1.south) node[and port, below=\baselineskip] (myand2) {2}% 0 would be touching
    %(myand2.in 1) to[short,-*] (2,0 |- myand2.in 1)
    (myand2.in 1) node[circ]{}% since they are already touching
    (prvone.out) |- (myand2.in 2)
    ;
\end{circuitikz}
\end{document}
