INS8255 Overview
The INS8255 is a programmable peripheral interface contained in a standard, 4().pin dual·in·line package. The chip, which is fabricated using N·charinel silicon gate technology, functions as a general·purpose parallel input/output interface in National Semiconductor's N8080 microputer family. The functional configura· tion of the INS8255 is programmed by the system software so that normally no external logic is...
