Mirrored Pinout 
Improve PC Board Design
by Using Mirrored Pinout

  • MirrorChipTM Mirrored Pinout


  • Intermix mirrored pinout and standard ICs to optimize PC board design.
  • Create smaller boards with fewest inner layers.
  • Use Mirrored pinout devices on same side or opposite side of board.


  • "Mirrored Pinout" devices are wired in clockwise rotation. Standard IC packages are wired in counterclockwise rotation. By combining MirrorChipTM with standard integrated circuits you can design smaller circuit boards with fewer layers at lower cost.

    The resulting circuit is simplified
    with point-to-point wiring on a single layer.

    By mounting a standard IC on the top side of the board with a Mirrored Pinout IC directly under it on the other side, the size of the board shrinks, allowing smaller black boxes and lighter total systems. Copper tracing lengths dramatically reduce and performance improves. Speed increases 1 nano second faster for each 6-inch (150mm) reduction in copper etch. Cost is reduced by decreasing the number of board inner layers, with less raw materials (gold, silver, copper).

    "U2" mirrored pinout device on bottom side

    Circuit tracings between pins of U1 and U2 is 2mm.
