Condition : (Refer to test circuit.)

Ta= 25 degC, VDD=VIH=3.3V, VOUT=0.7V, VIL=0V, REXT=490ohms, VL=3.0V, RL=60ohms, CL=10.5pF

Note 1 : When tf / tf of clock wave form is enlarged at the time as the cascade connection,

the timing condition which is necessary for the data transfer may not be able to be secured.

Give careful consideration to the timing condition.
