Abstract

PURPOSE:To make the titled circuit suitable for high density circuit integration by forming a flip-flop circuit operated in two way so as to set freely the input/ output of a signal depending on the design status at that time. CONSTITUTION:Two flip-flops 9a, 9b without directivity are constituted by inserting transmission gates 6, 7 in series with the output side of inverters 3a, 3d at the master and slave side not having the transmission gate in a conventional master slave flip-flop where inverters are connected as a loop and the flip-flops are connected in series. Thus, the unit circuit being the input side is the master and the unit circuit being the output side is the slave circuit, the titled circuit is used in two-way and the input/output is set in matching with the other circuit, then the share of the circuit wiring occupied in the circuit is reduced and the degree of freedom in the design is improved.
