Application Scenarios & Design Considerations

4 Digit (LED) Presettable Up/Down Counter

Alternative Part Number

  • ICM7217AIPI --: Same ICM7217 4-digit programmable timer/counter family in a 28-pin PDIP package; the A grade is a direct functional substitute with slightly different electrical specifications, making it the closest drop-in option.
  • ICM7226BIPI --: Intersil 4.5-digit counter/timer IC in a comparable DIP package with similar display-drive and counting functions; usable as a functional alternative when minor pin and feature differences are acceptable.
  • MAX7217CPI --: Maxim part derived from the same Intersil ICM7217 design lineage, offering equivalent programmable counter/timer functionality in a DIP package; a viable second-source style alternative for legacy designs.
  • ICM7217BIPI --: Another grade variant of the same ICM7217 programmable counter/timer in the same PDIP package, electrically compatible and usable as a drop-in replacement in most designs.
