AuthorMarley, Bob (Robert) R.
Biographical NotesRobert (Bob) Russell Marley earned an M.S.E.E. from the California Institute of Technology in 1964. He joined the General Electric Computer Division in Phoenix and moved on to Motorola as an ECL circuit design engineer in 1966. He joined Fairchild R&D in 1968 where he worked for his former Motorola supervisor, Walter Seelbach. He designed the Fairchild 100K series ECL family before returning to Motorola in 1971. He became an independent consultant in 1977 and continued to file patents assigned to Motorola through the mid-1980s.

DescriptionDescribes logic functions and circuit schematics for high speed CML and ECL logic ICs of SSI (Small Scale Integration) and MSI (Medium Scale) complexity. All circuits use temperature compensation schemes designed to minimize logic level mismatch between packages operating at different temperatures. Includes a Divide by 10:11 Prescaler that became one of Fairchild’s largest selling ECL devices. It was typically used in communications systems outside the typical computer application for ECL devices.
