Description and Introduction

8-Bit Serial-Input Latched Drivers # **Introducing the MIC5842BN: A High-Performance Serial-Input Latched Driver**  

The MIC5842BN is a versatile and reliable serial-input latched driver designed to meet the demands of modern electronic applications. This high-performance component is engineered to deliver precise control and efficient power management, making it an ideal choice for a wide range of industrial, automotive, and consumer electronics applications.  

Featuring an 8-bit serial-in, parallel-out shift register with latched outputs, the MIC5842BN ensures seamless data transfer and stable signal integrity. Its built-in Darlington transistor array provides high-current sinking capability, enabling direct control of inductive loads such as relays, solenoids, and LEDs. With a maximum output voltage of 50V and a continuous current rating of 500mA per channel, this driver offers robust performance in demanding environments.  

One of the key advantages of the MIC5842BN is its compatibility with standard logic levels, allowing for easy integration into existing digital systems. The device includes an open-collector output structure, ensuring flexibility in interfacing with various loads. Additionally, its serial input capability reduces the number of required control lines, simplifying PCB design and minimizing system complexity.  

Designed for durability, the MIC5842BN incorporates thermal shutdown and output clamp diodes for enhanced protection against voltage spikes and overheating. These features contribute to extended operational lifespan and improved reliability in harsh conditions.  

Whether used in industrial automation, automotive control systems, or LED display drivers, the MIC5842BN delivers consistent performance and efficiency. Its compact DIP package ensures straightforward implementation, while its robust design guarantees long-term stability.  

For engineers and designers seeking a dependable, high-current driver with serial interface capabilities, the MIC5842BN stands out as a superior solution. Its combination of power, precision, and protection makes it an essential component for next-generation electronic systems.

Application Scenarios & Design Considerations

8-Bit Serial-Input Latched Drivers

Alternative Part Number

  • ULN2803A --: Eight-channel Darlington sink driver in a DIP package, functionally equivalent to the MIC5842 8-bit serial-input driver for relay/LED loads.
  • TPIC6595N --: 8-bit serial-in shift register with power DMOS outputs in DIP, similar serial-input driver function and output current capability.
  • MC1413BDG --: Seven-channel Darlington array in DIP, widely used as a drop-in style driver replacement for Micrel 5800-series sink drivers.
  • UCN5842A --: Direct functional equivalent 8-bit serial-input latched sink driver with the same pinout and output ratings, widely available from Allegro.
  • MC33996 --: 16-output serial low-side driver that can cover the same application with more channels, though pinout and package differ so layout changes are required.
