INS8238 Overview
The INS8228/INS8238 is a system controller/bus driver contained in a standard, 28-pin dual-in-line package. The chip, which is fabricated using Schottky Bipolar technology, generates all the read and write control signals required to directly interface the memory and input/output ponents of National Semiconductor's INS8080A microputer family. The chip also provides drive and isolation for the bidirectional data bus...
