    • PROBLEM TO BE SOLVED: To provide a scan flip-flop which is a hold-free small test circuit, and allows a test with an actual operation frequency to be possible.SOLUTION: A Pos type F/F 100 has: a master latch (Low level latch) 110 which is synchronized with a rising edge of a clock and in which data or scan test data is selectively input; and a slave latch (Hi level latch) 111 in which the data from the master latch 110 is input. Then, in scan shift, the master latch 110 fetches scan shift data input SIN in a Low period of a scan shift clock SCLK1 and outputs the fetched scan shift data input SIN to the slave latch 111. The slave latch 111 fetches output of the master latch 110 in a Hi period of a scan shift clock SCLK2 at an edge position different from that of the SCLK1 and outputs the fetched output of the master latch 110 to Q.
