NEe Microcomputers, Inc. fttIEC Jl,PB8228 J.I PB8238 8080A SYSTEM CONTROLLER AND BUS DRIVER OESCR IPTION The pPB8228/8238 is a single chip cOntroller and bus driver for 8080A based systems. All the required interface signals rrecessary to connect RAM, ROM and I/O components to a pPD8080A are generated. The pPB8228/8238 provides a bi directional three state bus driver for high TTL fan-out and isolation of the processor data bus from the system data bus for increased noise immunity. .
