![]() ![]() ![]() The formation of shift registers is dependent on the latches used. The number of bits is directly proportional to the number of latches used. These registers are comprised of latches which are of D-type. The basic purpose of these circuits is to store and transfer the data. These circuits are influenced by both present stage inputs and Past values. Shift Registers are the logic circuits of sequential type. ![]() To the conversion of data from parallel to serial, these registers are used. These registers play a vital role in long distance communication (like UART) between two processors to avoid the complexity of parallel wiring and its slow data transmission. The ānā number of stages in the register is proportional to the delay generated in the circuit by n times. To send data bits into the microprocessors/ microcontrollers and for reading data out these, shift registers are used. These Sequential circuits are used to generate certain delays in the digital waveforms or signals. Shift Registers are constructed using latches or the Flip-Flops. ![]()
