Shift Registers
Shift Registers
are combination of number of Flip Flops. These are
connected in a way that input signal is given to first
flip flop and data is transported to another flip flop
after another clock pulse is applied. Shift Registers
are commonly used in Digital Electronics Circuits for
storage of Binary data and delay of signals. The
parallel data gets loaded into register as
Serial/Parallel Control input goes High. We can use
these registers for converting serial input data into
parallel output and parallel input data into serial
output. The parallel loaded number is shifted out
serially by clock pulses. We can serially shift out
parallel loaded number and keep that number in the
register by connecting last output to the serial input.
Shift Registers are used for conversion
of serial input data into parallel output data and vice
versa. Shift Registers are a group of flip flops. Binary
data can be shifted from one flip flop to next on each
clock pulse.
Serial Data transfer is slower than the
parallel data transfer because data goes through only
one line whereas in parallel each bit requires its own
separate path. Parallel Data can be cleared faster and
requires less hardware.
Shift registers
are a type of sequential logic circuit, mainly for
storage of digital data
