Description and Introduction

8-Bit Serial-Input Latched Source Driver **Enhance Your Design with the MIC5891BN High-Current Shift Register**  

The MIC5891BN is a high-performance, 8-bit serial-in, parallel-out shift register designed to simplify high-current applications. With its robust output drivers capable of sourcing up to 350mA per channel, this component is ideal for driving LEDs, relays, and other high-power loads with precision and reliability.  

Engineered for efficiency, the MIC5891BN features a serial data input and output, allowing for easy daisy-chaining in multi-device configurations. Its built-in latch ensures stable output states, while the open-drain outputs provide flexibility for both sinking and sourcing current. The device operates over a wide voltage range (4.5V to 15V), making it compatible with various logic levels and power supply conditions.  

Key advantages of the MIC5891BN include thermal shutdown protection, which safeguards the device from overheating, and a low standby current, enhancing energy efficiency in battery-powered applications. Its rugged design ensures durability in industrial environments, where consistent performance under demanding conditions is essential.  

Whether used in LED displays, industrial control systems, or automation projects, the MIC5891BN delivers reliable, high-current drive capability while minimizing design complexity. Its compact DIP package allows for straightforward integration into existing circuits, reducing development time and cost.  

For engineers seeking a dependable shift register with high output drive, the MIC5891BN offers a proven solution that balances performance, efficiency, and ease of use.

Application Scenarios & Design Considerations

8-Bit Serial-Input Latched Source Driver

Alternative Part Number

  • TPIC6595N --: 8-bit serial-in parallel-out power shift register with high-current outputs, functionally similar to the MIC5891 and widely available in a DIP package.
  • UDN2981A --: 8-channel source driver with high-current outputs, commonly used as a drop-in style replacement for serial driver applications in DIP form.
  • MC1413BDG --: Seven-channel Darlington sink driver in DIP, a common general-purpose high-current driver alternative when sink-type outputs are acceptable.
