除非你完全清楚自己在做什么，否则永远不要混淆 Ti 的内部电路库钾Z circuitikz；它有记录在手册的开头。
您可以使用muxdemux中的（高度可配置）组件获得一个非常相似的解码器circuitikz。请参阅此处的示例，其中注释解释了您可以找到的键的值在手册中。
\documentclass[border=10pt]{standalone}
\usepackage{circuitikz}
% define the component
\tikzset{my3to8/.style={
muxdemux, muxdemux def={
Lh=8, Rh=8, w=6, % both left and right size =8 units, wide top
NT=1, NB=0, % one terminal on the top, none bottom
NR=8, % 8 pins on the right
% we will define 9 pins on the left, to have them
% centered, but we will draw just the central three
NL=9,
},
draw only left pins = {4-6},
}
}
\begin{document}
\begin{tikzpicture}[]
\draw (0,0) node[my3to8](D){\tiny\ttfamily 3:8 decoder};
% left labels
\foreach \i [count=\iz from 0] in {1,...,8} {
\node[left, font=\tiny\ttfamily] at (D.brpin \i) {\iz};
\node[right, font=\tiny\ttfamily] at (D.rpin \i) {Y\iz};
}
% right labels
\foreach \i/\lab [count=\iz from 0] in {4/d,5/c,6/b} {
\node[right, font=\tiny\ttfamily] at (D.blpin \i) {\iz};
\node[left, font=\tiny\ttfamily] at (D.lpin \i) {\lab};
}
% top label
\node [below, font=\tiny\ttfamily] at (D.btpin 1) {EN};
\node [above, font=\tiny\ttfamily] at (D.tpin 1) {a'};
\end{tikzpicture}
