TitleBeeson laboratory notebook (#1)
DescriptionThis lab notebook is described by the author as a supplement to his patent notebooks. It contains brief notes on testing and associated results. Page 47 includes further exploration of the TTL circuit disclosed in Beeson (146).
Biographical NotesR.H. Beeson joined Fairchild circa mid-1958 and remained at least until mid-1961. He worked for Vic Grinich on the application of transistors for high-speed switching in logic applications. He independently invented the Transistor Transistor Logic (TTL) logic configuration that was described in the 1962 ISSCC paper “New Forms of All-Transistor Logic” co-authored with H. W. Ruegg. Commercialized by Sylvania and copied and successfully promoted by Texas Instruments, TTL formed the workhorse digital IC family of the 1970s. In the late 1960s he was working for Amelco Semiconductor.
