These products can directly drive VFDs with up to 38 segments. Package Dimensions unit: mm 3061-DIP30S [LC7573N] Features • 38 segment outputs • Noise reduction circuits are built into the output drivers. • Serial data input supports CCB* format communications with the system controller. • Switching between digital and analog dimmers under serial data control • High generality since display data is displayed without the intervention of a decoder • All segments can be turned off with the BLK pin SANYO: DIP30S • CCB is a trademark of SANYO ELECTRIC CO., LTD. • CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO. unit: mm 3073A-MFP30S [LC7573NM] Pin Assignment SANYO: MFP30S SANYO Electric Co.,Ltd.
