Bidirectional Shift Register Timing Diagram. In right shift operations the binary data is divided by two. Ic 74671 4 bit bidirectional shift register.
Floyd figure 6 1 the 74hc194 4 bit bi directional universal shift register figure 6 2 the timing diagram of 74hc194. The timing diagram of the device is also. This question reviews the principles of d type flip flops timing diagrams and serves as an introduction to shift registers.
Similarly if a binary number is shifted right by one position then it is equivalent to dividing the original number by 2.
The input data is connected at two ends of the circuit and depending on the mode selected only one and gate is in the active state. Ic 74673 16 bit serial in serial out shift register with output storage registers. Bidirectional shift registers are the storage devices capable of shifting the data either right or left depending on the mode selected. If a binary number is shifted left by one position then it is equivalent to multiplying the original number by 2.
