［Truth Table］
After the power is turned on and the voltage is stabilized, LCK should be activated, after clocking 12 data bits into
the DATA terminal.
Qx parallel output data of the shift register is set after the 12
Since the LCK is a label latch, data is retained in the “L” section and renewed in the “H” section of the LCK.
Data retained in the internal latch circuit is output when the OE is in the “L” section.
