MC14489BDWE Product details

Multy-Character LED Display/Lamp Driver CMOS



The  MC144898  is  a flexible  light-emitting-diode  driver  which  directly  in terfaces  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.



.Operating  Voltage  Range  of  Drive  Circuitry:  4.5  to  5.5  V

.Operating  Junction  Temperature  Range:  -40°  to  130°C

.Current  Sources  Controlled  by  Single  Resistor  Provide  Anode  Drive

.Low-Resistance  FET  Switches  Provide  Direct  Common  Cathode  Interface

.Low-Power  Mode  (Extinguishes  the  LEDs)  and  Brightness  Controlled  via Serial  Port

.Special  Circuitry  Minimizes  EMI  when  Display  is  Driven  and  Eliminates  EMI in  Low-Power  Mode

.Power-On  Reset  (POR)  Blanks  the  Display  on  Power-Up,  Independent  of Supply  Ramp  Up  Time

.May  Be  Used  with  Double-Heterojunction  LEDs  for  Optimum  Efficiency

.Chip  Complexity:  4300  Elements  (FETs,  Resistors,  Capacitors,  etc.)
