What is a Universal Shift Register?
Universal Shift registers are an integral part of digital memory circuitry usually found in devices such as calculators, computers, and data processing systems. With a universal shift register, data or bits can be entered into the system in a serial or parallel manner. Data entry using 74LS195 is usually done from one direction, and as more data is added, it shifts positions until the data gets to the output end. The two ends are referred to as the left and right end. The movement of data can be from left to right, from right to left, or in both directions to make a bidirectional shift register.
