ABSTRACT:
A clock synchronous serial information transfer apparatus, comprises, a control signal circuit 6 which inputs a clock CLKin, and judges that the same level has continued over a predetermined time to output the judging result as two complementary control signals CLKa and CLKb, latch circuits 9a to 16a operated by a control signal which outputs a high level when the clock CLKin inputted to the control signal circuit 6 has kept the high level, and latch circuits 9b to 16b operated by a control signal which outputs the high level when the clock CLKin inputted to the control signal circuit 6 has kept a low level, whereby data is transmitted and received correctly even when noises occur in the clock CLKin.
