Universal Shift Register Diagram. A commonly used universal shift register is the ttl 74ls194 as shown below. A universal shift register is a register which has both the right shift and left shift with parallel load capabilities.
Though separate in the diagram the keypad and display are both contained within the same remote enclosure. A universal shift register is a register which has both the right shift and left shift with parallel load capabilities. The functional diagram of the shift register is shown below.
Now we will combine both the keypad and display into a single unit using a universal shift register.
In other words a combined design of unidirectional either right or left shift of data bits as in case of siso sipo piso pipo and bidirectional shift register along with parallel load provision is. A universal shift register is a do everything device in addition to the parallel in parallel out function. A unidirectional shift register is capable of shifting in only one direction. Ic 74291 4 bit universal shift register binary up down counter synchronous.
