A new family of transistor switching circuits

OVER THE PAST 10 years, electronic switching circuits have found their way into numerous pieces of equipment in many fields of endeavor. The circuits are carefully designed prototypes intended to serve with utmost reliability and in large numbers in serial or parallel digital computers, in control systems, in communications equipment or in dial telephone switching offices.1¿4 The specific prototype circuit may be designed around vacuum tubes, diodes, magnetic devices, or transistors, as influenced by the system in which it is to be used. The existence of numerous basically different prototype circuits is indicative of the large variation in system goals; new families of switching circuits offer certain advantages in existing systems and open the door to new system applications. The family to be described in this paper is a new prototype available to the system designer.
