This is a Serial In - Parallel Out or Serial Out [SIPO or SISO] shift register using the flip-flops found in the 4013. The circuit is shown bellow. At each cycle of the clock, data applied to the input is shifted one cell to right. Shift registers can be used as memory. The number of bits stored depends on the number of flip-flops. The maximum input frequency is 12.5 MHz when the circuit is powered from a 10 V supply.
