4-Bit Bidirectional Universal Shift Registers
General Description
These bidirectional shift registers are designed to incorpo-
rate virtually all of the features a system designer may want
in a shift register they feature parallel inputs parallel out-
puts right-shift and left-shift serial inputs operating-mode-
control inputs and a direct overriding clear line The register
has four distinct modes of operation namely
Parallel (broadside) load
Shift right (in the direction QA toward QD)
Shift left (in the direction QD toward QA)
Inhibit clock (do nothing)
Synchronous parallel loading is accomplished by applying
the four bits of data and taking both mode control inputs S0
and S1 high The data are loaded into the associated flip-
flops and appear at the outputs after the positive transition
of the clock input During loading serial data flow is inhibit-
Shift right is accomplished synchronously with the rising
edge of the clock pulse when S0 is high and S1 is low
Serial data for this mode is entered at the shift-right data
input When S0 is low and S1 is high data shifts left syn-
chronously and new data is entered at the shift-left serial
Clocking of the flip-flop is inhibited when both mode control
inputs are low
Parallel inputs and outputs
Four operating modes
Synchronous parallel load
Right shift
Left shift
Do nothing
Positive edge-triggered clocking
Direct overriding clear
Typical clock frequency 105 MHz
Typical power dissipation 425 mW
