The active-low asynchronous Reset overrides the Clock and Serial Data inputs. Data is entered on each rising edge of the clock. Two serial data inputs, A1 and A2, are provided so that one input may be used as a data enable. The IN74AC164 is an 8-bit, serial-input to parallel-output shift register. The device inputs are compatible with standard CMOS outputs with pullup resistors, they are compatible with LS/ALS outputs. This shift can be of two types either left, right or both based on the mode selected.1 TECHNICAL DATA IN74AC164 8-Bit Serial-Input/Parallel-Output Shift register High-Speed Silicon-Gate CMOS The IN74AC164 is identical in pinout to the LS/ALS164, HC/HCT164. As per the name shift, the data bits are shifted for the purpose of transferring the data. The Flipflops connected in the number of stages can be used for various purposes in the digital circuits.

The below code is for a Shift Left Register of 8 bits ‘Serial In and Serial Out’ with a Positive edge.

The above are some of the applications of shift registers.

To convert data from serial to parallel and parallel to serial.

To generate Delays in the circuit these are preferred.

These are used in ‘Finite Memory Machines’.

The chain of Flip-flops connected together acts as a memory element.

This difficulty can be overcome by using an additional gate.įurther, there are various applications of shift registers. The most widely used counters of this type are:īut both the counters can suffer from a condition called ‘Lock-out’. The output of the last stage of the register is fed back to the first stage, forming a ring. These are designed based on the serial input applied and output derived serially. CountersĬounters are one of the applications of shift registers. The combination of ‘Unidirectional’ and ‘Bidirectional’ Registers with a Parallel Load provision can be referred to as Universal shift Registers. By shifting the bits either left or right. It can be either in serial or parallel mode. The registers are capable of loading and retrieving the data. This is a special case of shift registers. Similarly, the value of the mode is chosen as 0 the circuit operates as Left Shift Register. If the mode is set to high that is selected as 1 then the circuit operates as Right Shift Register. If the bit is shifted right by one position that is in equivalence to the bit divided by 2.Īmong the two directions, one can be chosen based on modes in the single circuit. If the value of the bit is shifted ‘left’ by one position resembles that the bit is multiplied by ‘2’. The data transfer or the data taken for storage can follow the process of parallel or serial both. The most frequently used one is the register with eight bits. 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 ‘n’ 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.
