It has the same high speed performance of LSTTL combined with true CMOS low power con- sumption. This SHIFT REGISTER is designed to in- corporate virtually all of thefeaturesasystem designer may want in a shift register. It features parallel inputs, parallel outputs, right shift and left shift serial inputs, clear line. The register has four distinct modes of oper- ation : PARALLEL (broadside) LOAD ; SHIFT RIGHT (in the direction Q A Q D ); SHIFT LEFT ; INHIBIT CLOCK (do nothing). Synchronous parallel loading is accomplished byapplying thefour databitsand taking both mode control inputs, S0 and S1 high. The data are loaded into their respective flip-flops and appear at the outputs after the positive transition of the CLOCK input. During loading, serial data flow is in- hibited. 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 shiftsleft synchronously and new datais en- tered at the SHIFT LEFT serial input. Clocking of the flipflops isinhibited when bothmode control inputs are low. The mode control inputs should be changed only when theCLOCKinput ishigh. All inputs areequipped with protection circuits against static discharge and transient excess voltage.
