AND-OR logic circuit including a feedback path

摘要

A plurality of logical product signals, from an AND circuit having a plurality of series circuits of transistors of a first conductivity type which selectively receive input signals, are selectively supplied to the gates of transistors of a second conductivity type which constitute an OR circuit and which are selectively connected in parallel between a power source and output signal lines. The AND and OR circuits are respectively controlled by synchronizing signals of opposite phases.
