MIC5842BN

Overview

The MIC5842BN is an 8-bit serial-input latched driver manufactured by Microchip Technology. It features a BiCMOS process and is housed in an 18-pin DIP package. The device operates within a temperature range of -40°C to +85°C. It functions as a SIPO-based peripheral driver with sink output current capability. The component includes built-in transient protection and utilizes a single function interface type.

Feature Summary

• Serial input latched architecture for efficient data handling
• BiCMOS technology integration for robust performance
• Built-in transient protection mechanisms

Applications

• Motor driving systems
• Relay control circuits
• Solenoid actuation applications

Procurement Notes

Verify the specific manufacturer designation, as historical records indicate Micrel Semiconductor as the original producer before acquisition by Microchip Technology. Confirm package integrity for the 18-DIP configuration. Ensure compliance with industrial temperature specifications ranging from -40°C to +85°C during procurement validation.

Selection Notes

Select this component when an 8-bit serial interface is required for high-current load management. The BiCMOS process offers a balance of speed and drive capability suitable for inductive loads. Consider the DIP packaging for through-hole assembly requirements in legacy or high-reliability designs.

Part Context

This part belongs to the MIC5842 series of serial input latched drivers. It is designed to replace older discrete driver solutions by integrating eight channels into a single IC. The series is optimized for controlling external power switches or direct low-voltage loads in embedded systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The MIC5842BN is listed as obsolete in some distributor catalogs; verify availability status with authorized Microchip distributors.
