Figure 5 Operation Timing
The high level of the enable-input signal (when SHL = V
CC
: EIO1) is latched at the rising edge of the
data-latch clock signal CL2, and data latching begins after one CL2 signal cycle. Data of 6 bits

2 pixels, i.e. 6 outputs are simultaneously latched at the rising edge of the CL2 signal. At the rising
edge of the 64th clock pulse of the CL2 signal, the enable-output signal (when SHL = V
CC
: EIO2) is
driven high, and the operation is automatically halted (the standby state is entered) when latching of
data for 384 outputs is completed. By connecting the EIO2 pin to the next-stage EIO1 pin, the next-
stage IC is activated in the same way.
The data-latch clock signal CL2 does not require a clock-halted period. Two-clock period (min.) after
final-data input in one horizontal period is a blanking period, and data input is invalid in this period.
At least two clocks of the CL2 signal must be input during the high-level period of the CL1 signal.
