Transistor Shift Registers

Three different types of high-speed transistor shift registers are discussed. The high speed (3 to 5 microseconds per shift pulse) is made possible by the use of nonsaturating bistable circuits. Two general shift registers are described making use of respectively one and two transistors per stage. The third register is of a specialized variety capable of shifting a single digit. In addition, an analysis is made of the triggering requirements of the register using a single transistor per stage.
