Product Description
MBI5025  is  designed  for  LED  displays.  As  an  enhancement  of  its  predecessor,  MBI5016,
MBI5025  exploits  PrecisionDrive™  technology  to  enhance  its  output  characteristics. MBI5025 contains  a  serial  buffer  and  data  latches  which  convert  serial  input  data  into  parallel  output format.  At  MBI5025  output  stage,  sixteen  regulated  current  ports  are  designed  to  provide uniform and constant current sinks for driving LEDs within a large range ofVf variations.
