ABSTRACT:
A semiconductor integrated circuit includes a first shift register composed of a plurality of first flipflops each including a first selector for selecting a first or second clock, a second selector for selecting an inverted signal of the first clock or a third clock, a third selector for selecting a first data signal or a first scanning signal, a first latch circuit for latching an output of the third selector, and a second latch circuit for latching an output of the first latch circuit. The semiconductor integrated circuit further includes a second shift register composed of a plurality of second flipflops each including a fourth selector for selecting a second data signal or a second scanning signal, a third latch circuit for latching an output of the fourth selector, and a fourth latch circuit for latching an output signal of the third latch circuit.
