Application Scenarios & Design Considerations

8-Digit, Microprocessor- Compatible, LED Display Decoder Driver

Alternative Part Number

  • MAX7228BIBI --: Same 8-digit LED display driver function and pinout, direct functional equivalent from a different series.
  • MC14489B --: Similar 8-digit LED display driver/controller with multiplexed output, suitable replacement with minor circuit adaptation.
  • ICM7218BIJI --: Related Intersil 8-digit LED display driver in the same family but different series suffix, usable with pin-compatible design.
  • MAX7219CNG+ --: Widely available 8-digit LED display driver in a DIP package that can replace the ICM7228B display driver function in many designs, with better long-term availability.
  • MC14489BDWE --: Multiplexed 5-digit LED display driver with serial interface that offers comparable display driving capability and is a viable alternative when exact pin compatibility is not required.
