Application Scenarios & Design Considerations

Dual Very-High Speed, High-Current Peripheral Drivers

Alternative Part Number

  • MC1413BDG --: High-voltage high-current Darlington array in the same peripheral driver family, widely available and pin-compatible for many relay/LED driver applications.
  • ULN2003AN --: Classic Darlington transistor array with similar sink-current capability, commonly used as a drop-in replacement for multi-channel driver tasks.
  • DS75453N --: Direct functional equivalent of the SN75453B dual peripheral driver, offering the same logic and output drive characteristics.
