ABSTRACT:
A laterally formed PNP transistor includes twenty-four approximately equal area emitters aligned in two rows in spaced relationship, each emitter being adjacent to another emitter and having for collectors formed thereabout to produce ninety-six collector outputs. Certain collectors between adjacent emitters and between rows are merged together with predetermined ones of the collectors associated with different emitter regions being interconnected.
