Features
鈥?1/2 duty, 1/2 bias drive of up to 54 segments
鈥?Serial data input supports CCB* format communication
with the system controller.
鈥?Backup function which is based on a power saving
mode and all segments off functions that are controlled
by serial data.
鈥?High generality, since display data is displayed directly
without decoder intervention.
鈥?The display can be forced to the off state with the INH
pin.
鈥?RC oscillator circuit
鈥?CCB is a trademark of SANYO ELECTRIC CO., LTD.
鈥?CCB is SANYO鈥檚 original bus format and all the bus
addresses are controlled by SANYO.
