Standard ICs FL tube driver BU2872AK The BU2872AK is a driver IC for the FL display unit.
It has a total of 22 high withstanding voltage output pins, and supports displays ranging from 11-segment 11-character displays to 16-segment 4-character displays.
A key scan function, LED drive output, and a general-purpose input pin make this IC ideal for use in the front panels of VTRs and other equipment.
A serial interface enables control of all functions through a microcomputer.
