<p>PURPOSE:To operate a flip-flop circuit with one transfer clock by providing a data storage circuit and a switch circuit consisting of an MOSFET in the master side as well as the slave side. CONSTITUTION:A signal M of a data storage circuit 6 in the master side turns on a switch circuit 8 and goes to the low level forcibly if an anti-phase input data signal DIN is in the high level and a transfer clock signal CL1 is in the high level. Similarly, a switch circuit 7 is turned off, and the anti-phase signal M goes to the high level. If the input data signal DIN is in the high level, the switch circuit 7 is turned on, and the anti-phase signal M goes to the low level forcibly, and the switch circuit 8 is turned off, and the signal M goes to the high level. Thus, input data DIN can be transferred to the data storage circuit 6 in the master side when the clock signal CL1 is in the high level. Similarly, stored data in the master side can be transferred to a data storage circuit 9 in the slave side when a transfer clock signal CL2 is in the low level. Consequently, this flip-flop circuit is operated with one transfer clock.</p> |
