●Timing chart
Fig. 2
1. After the power is turned on and the voltage is stabilized, STB should be activated, after clocking 8 data bits into the
DATA pin.
2. Pn parallel output data of the shift register is set after the 8
th clock by the STB.
3. Since the STB is level latch, data is retained in the “L” section and renewed in the “H” section of the STB.
［Function explanation］
·
A latch circuit has the reset function, which is common in all bits. In case of CLR terminal is “L”, the latch
circuit is reset non-synchronously without the other input condition, and all parallel output can be “L”.
·
A serial data inputted from DATA terminal is read in shift register with synchronized rising of clock.
In case of STB is “L” (CLR is ”H”), transmit the data which read in the shift register to latch circuit, and
outputs from the parallel data output terminal (P1～P8).
In case of STB is “H”, all parallel outputs and the data of latch do not change.
