Abstract

PURPOSE:To obtian uniform low-level output voltage characteristics, by making the emitter current density of the constant-current transistor of the current switch circuit equal to that of the output emitter-follower transistor during low-level outputting in the current-alternation-type logic circuit which has an output emitterfollower.
