4 Bit Shift Register Ic. 74hc165 parallel in serial out shift register. The data is transferred from the serial or parallel d inputs to the q outputs synchronous with the high to low transition of the appropriate clock input.
Parallel broadside load shift right in the direction qatoward qd shift left in the direction qdtoward qa inhibit clock do nothing synchronous parallel loading is accomplished by applying the four bits of data and taking both mode control inputs s0 and s1 high. The sn54 74ls95b is a 4 bit shift register with serial and parallel synchronous operating modes. The block diagram of 3 bit sipo shift register is shown in the following figure.
This circuit consists of three d flip flops which are cascaded.
What was on the first flip flop from before is stored on the second flip flop. Dual 4 bit ic having serial inputs and a parallel output shift register composed of 8 master slave flip flops. Ic 74671 4 bit bidirectional shift register. Four bit shift register using 74ls194 ic with porteus simulationfor more details.
