Universal Shift Register Ic. Above we apply four bit of data to a parallel in parallel out shift register at da db dc dd. Universal shift register is a register which can be configured to load and or retrieve the data in any mode either serial or parallel by shifting it either towards right or towards left.
They feature parallel inputs parallel outputs right shift and left shift serial inputs operating mode con. S1 is low and s0 is high. Shift right dsr q0 q0 q1 s1 and s0 are high.
It can be used to perform input output operations in both serial and parallel modes.
S1 is low and s0 is high. A unidirectional shift register is capable of shifting in only one direction. Shift right dsr q0 q0 q1 s1 and s0 are high. This register can perform three types of operations stated below.
