* When mounted on a 70mm ` 70mm ` 1.6mm glass epoxy boardDescriptionThe BU2872AK is a driver IC for the FL display unit. BU2872AK 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.
