8288A Bus Controller is a 20-pin bipolar component for use with medium-ta-large SAB 80186, SAB 80188, SAB 8086, and SAB 8088 processing systems. The bus controller provides command and control timing generation as well as bipolar bus drive capability while optimizing system performance. A strapping option on the bus controller configures it for use with a multi-master system bus and separate /0 bus.
