Universal Shift Register Ic. 4 bit universal shift register 74ls194. Parallel load i on qn note.
It is also known as a parallel in parallel out shift register or shift register with the parallel. In other words a combined design of unidirectional either right or left shift of data bits as in case. 4 bit bidirectional universal shift register general description this bidirectional shift register is designed to incorporate virtually all of the features a system designer may want in a shift register.
4 bit universal shift register 74ls194.
These universal shift registers can perform any combination of parallel and serial input to output operations but require additional inputs to specify desired function and to pre load and reset the device. Above we apply four bit of data to a parallel in parallel out shift register at da db dc dd. A bidirectional shift register is capable of shifting in both the directions. Universal shift registers are used as memory elements in computers.
