DESCRIPTION

The M54/74HC195 is a high speed CMOS 4 BIT
PIPO SHIFT REGISTER fabricated in silicon gate
C2MOStechnology. Ithasthesamehighspeedper­formance of LSTTL combined with true CMOS low
powerconsumption.

This shift register features parallel inputs, parallel
outputs, J-K serial inputs, a SHIFT/LOAD control
input,and a directoverridingCLEAR. Thisshift reg­istercan operate intwo modes : Parallel Load ;Shift
from QAtowards QD.

Parallel loadingisaccomplishedbyapplying the four
bits of data, and taking the SHIFT/LOAD control
inputlow. The datais loaded intotheassociated flip
flops and appears at the outputs after the positive
transitionof the clockinput.During parallel loading,
serial data flow is inhibited. Serial shifting occurs
synchronously whenthe SHIFT/LOAD controlinput
ishigh.Serial data forthis mode isenteredattheJ-K
inputs. These inputs allowthe first stageto perform
as a J-Kor TOGGLE flip flopas shown inthe truth­table.

All inputs are equipped with protection circuits
against static discharge transient excess voltage.
