== Description ==
IDE8255 (desigmed by [[Yarek]]) is the simplest IDE multiplexer (8bit to 16bit) that everyone can build. And its also the fastest, the data transfer rate is 173 KB/second.
It consists of port decoder, a [[8255 PPI chip]], 74LS139 chip as control gate and some diodes, resistors and capacitors. The most important is, that the 8255 can work in MODE 1 while reading.
