[Tex/LaTex] Circuitikz – IC circuit with relative coordinates

circuitikzcoordinatesnodes

I've represented an IC circuit using circuitikz, but it's a bit too rough to what I prefer. In particular I would like to use relative coordinates in this case and connect them to the “IC device'' so that I don't have to guess where to place components. I would also like to scale the figure and maintain the integrity of the circuit. (Remove scale = 1.4 to get the unbroken circuit)

Any suggestions?

\documentclass{article}
\usepackage{tikz}
\usepackage[siunitx,european,american]{circuitikz} 


\begin{document}
%----IC device: 555 astable timer, or square wave oscillator
\tikzstyle{icdev}=[draw, text width=6em, minimum height=8em]
\begin{tikzpicture}[every node/.style = {font = \footnotesize},scale = 1.4]
    \draw (0,4)
    to[short,o-] (0.8,4)
    to[/tikz/circuitikz/bipoles/length=0.7cm,R] (0.8,2.4)
    to[/tikz/circuitikz/bipoles/length=0.7cm,R] (0.8,1.8)
    to[/tikz/circuitikz/bipoles/length=0.7cm,C] (0.8,0.2) -- (0.8,0)
    to[short,-o] (0,0);
    \node (digichip) [icdev,xshift=3cm,yshift=2cm] {};
% top terminal pins - 4 RESET, 8 Vcc
    \path [draw](0.8,4) -| (2.5,3.4) node[below]{RESET} node[above left]{4};
    \path [draw](2.5,4) -| (3.5,3.4) node[below]{$V_{cc}$} node[above left] {8};
% bottom terminal pins - 1 GND  , 5 CTRL
    \path [draw](0.8,0) -| (2.5,0.6) node[above]{GND} node[below left]{1};
    \path [draw](2.5,0) -- (3.5,0)
        to[/tikz/circuitikz/bipoles/length=0.7cm,C](3.5,0.6)  
        node[above]{CTRL} node[below left]{5};
% leftside terminal pins - 7 DIS, 6 THR, 2 TRG
    \draw (0.8,2.6) -- (1.83,2.6) node[right]{DIS} node[above left]{7}
        (1.2,1.5) |- (1.83,2) node[right]{THR} node[above left]{6}
        (0.8,1.5) -- (1.83,1.5) node[right]{TRG} node[above left]{2};
% rightside terminal pin - 3 out
    \draw (4.17,2) node[left]{Out} -- (4.8,2) node[above left]{3};

for the scale problem, use [scale=1.4,transform shape] instead of [scale=] for the other item, not enough experience

[Tex/LaTex] tikz, tikz circuits, relative coordinates

You need to shift the dimension lines so they don't coincide with the circuit lines. Since you're using nodes to position your elements, you'll need to add the shift length to each coordinate specification, so (A) -- (B) would become ([yshift=1cm] A) -- ([yshift=1cm] B) if you wanted to shift the line from A to B up one centimetre (see Shift line connecting anchors for more information).

Instead of using \nodes for defining the points, I would suggest using \coordinates. They don't need an empty node text, and they don't take up any space, which makes alignment easier. They don't have any anchors (apart from center), so you don't need to decide which anchor to use.

\documentclass{article}  
\usepackage{tikz}  
    \usetikzlibrary{circuits.ee.IEC,positioning}  
\begin{document} 
% circuit with relative coordinates  
\begin{tikzpicture}[circuit ee IEC, >=stealth',%  
    set resistor graphic = var resistor IEC graphic]  
    \coordinate (A)                     ;  
    \coordinate [above = 2cm of A] (B)  ;    
    \coordinate [right = 3cm of B] (C)  ;    
    \coordinate [right = 3cm of A] (D)  ;    
\draw (A) -- (B)  
    (B) to[resistor={info'={R}}](C)  
    (C) -- (D)  
    (D) to [battery={info'={$V$}}](A);  
\draw [<->] ([xshift=-0.5cm]A) -- ([xshift=-0.5cm]B) node[midway,fill=white]{\small{y cm}}; %!  
\draw [<->] ([yshift=0.5cm]B) -- ([yshift=0.5cm]C) node[midway,fill=white]{\small{x cm}}; %!

[Tex/LaTex] How to define the default vertical distance between nodes

I don't really get the question so I hope this is what you wanted. If you include a full document (such that we copy paste and see the problem on our systems) things are much more easier.

Here, you can change the default setting within a scope but your block style had a node distance which was resetting every time it is issued. I've made it 2mm such that we can see the difference easier.

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
                    block/.style   ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
                    cloud/.style   ={draw, ellipse, minimum height=2em},
                    line/.style    ={draw,-latex'},
                    node distance = 1cm, 
                    auto]
    \node [block] (1st) {1st};
    \node [block, right= of 1st]  (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
    \node [block, above= of 2nd1] (2nd2) {2nd2};
    \node [block, below= of 2nd1] (2nd3) {2nd3};
    \node [block, right= of 2nd1] (3rd1) {3rd1};
    \node [block, above= of 3rd1] (3rd2) {3rd2};
    \node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
    \node [block, below= of 3rd1] (3rd4) {3rd4};
    \node [block, below= of 3rd4] (3rd5) {3rd5};

    \path [line] (1st) -- (2nd1);
    \path [line] (2nd1) -- (2nd2);
    \path [line] (2nd1) -- (2nd3);
    \path [line] (2nd2) -- (3rd3);
    \path [line] (2nd1) -- (3rd1);
    \path [line] (1st) -- (2nd1);
\end{tikzpicture}
\end{document}
