technology. It has the same high speed performance
ofLSTTL combined with true CMOS lowpower con-
sumption. This SHIFT REGISTER is designed to in-
corporate virtuallyallofthefeaturesasystemdesigner

parallel outputs, right shift and left shift serial inputs,

CLOCK(donothing). Synchronous parallel loading is
accomplished byapplyingthefourdatabitsand 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.Shiftright isaccomplished synchronously with
therisingedge ofthe clockpulse whenS0ishigh and
S1 is low. Serial data for this mode is entered at the
SHIFTRIGHT data input. When S0 is lowand S1 is
high,data shiftsleftsynchronously andnewdataisen-
tered at the SHIFT LEFT serialinput. Clocking of the
flipflopsisinhibited whenbothmodecontrolinputsare
low.Themodecontrol inputsshouldbe changedonly
whentheCLOCKinput ishigh.Allinputsareequipped
with protection circuits against static discharge and
transient excess voltage.
