ml9227 Oki Semiconductor, ml9227 Datasheet - Page 14

• Manufacturer Part Number: ml9227
• Description: 27-bit Duplex/triplex Vfd Controller/driver With Digital Dimming, Adc And Key Scan
• Manufacturer: Oki Semiconductor

Segment Data Input [Function Mode: 0 to 3]
• ML9227 receives the segment data when function mode 0 to 3 are selected.
• The same segment data is transferred to the 3 segment data latch correspond to GRID1 to 3 at the same time
• The segment data is transferred to only one segment data latch that is selected by mode data, when the function
• Segment output (SEG1 to 27) becomes High level when the segment data (S1 to 27) is High level.
