This driver is commonly used in industrial, automotive, and consumer electronics applications.

Application Scenarios & Design Considerations

Dual Peripheral Drivers

Alternative Part Number

  • MC1413BP --: Seven-channel Darlington array in a DIP-16 package, functionally similar to the SN75478P peripheral driver and widely available.
  • ULN2003APG --: High-voltage high-current Darlington transistor array in DIP-16, commonly used as a drop-in replacement for similar peripheral driver ICs.
  • TPIC6595N --: Power logic shift register/driver in DIP package from the same manufacturer, suitable when a serial-input driver is acceptable.
