After the power is turned on and the voltage is stabilized, LATCH should be activated, after clocking 16 data bits
into the S_IN terminal.
OUTn parallel output data of the shift register is set after the 16
The final stage data of the shift register is outputted to the SOUT by synchronizing with the rise time of the
CLOCK.
Since the LATCH is a label latch, data is retained in the “L” section and renewed in the “H” section of the LATCH.
Data retained in the internal latch circuit is outputted when the ENABLE is in the “L” section. When the ENABLE
is in the “H” section, data is fixed in the “H” section.
