Product Summary

The  MC144898  is a flexible  light-emitting-diode  driver  which  directly  interfaces  to  individual  lamps,  7-segment  displays,  or  various  combinations  of
both.  LEOs  wired  with  common  cathodes  are  driven  in  a  multiplexed-by-5
fashion.  Communication  with  an MCUIMPU  is established  through  a synchronous  serial  port.  The  MC 144898  features  data  retention  plus decode  and scan
circuitry,  thus  relieving  processor  overhead.  A  single,  current-setting  resistor
is the  only  ancillary  component  required.
