DocumentDescription
This volume continues the testing of transistor switching characteristics from Beeson (p. 20). Other topics include, circuits for measuring RTH in avalanche mode that resulted in TR33 and NEC paper (below); note re. data taken in author’s absence by D. Farina for DCTL; note regarding J. Last’s “solid-state flip-flop” (p. 33); idea for stereo amplifier system using a single amp circuit; evaluation of TDL and LLL logic configurations; tunnel diode study (p. 110).Date

Beeson, R.H.Biographical Notes
R.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.Publisher
