FUNCTION DESCRIPTION
1.Data Input
Note 1)
At the leading edge of the CPS input , the status of the SI input is written into the shift
register .
Note 2)
The bit just before LE becomes "H" is LSB , and SI before MSB becomes invalid .
Note 3)
When LE is "H" , the data stored in the shift registers is loaded into the appropriate latch .
2.Input Signal Timing
