Overview
The MIC5842BWM is an 8-bit serial-input latched driver manufactured by Microchip Technology. It utilizes BiCMOS technology and is housed in a 18-pin SOIC wide package (SOP). The device features sink-type outputs capable of handling up to 50V load voltage. It operates within a temperature range of -40°C to +85°C. The component functions as a shift register with serial-to-parallel conversion, utilizing a single input line and rising-edge triggering.
Feature Summary
- Provides 8-bit serial-to-parallel data conversion for peripheral driving applications
- Features internal latch mechanism to maintain output states independently of clock signals
- Incorporates transient protection for enhanced reliability in industrial environments
Applications
- Driving high-voltage loads such as solenoids or lamps
- Industrial control systems requiring isolated peripheral interfacing
- Automotive electronics modules needing robust driver circuits
Procurement Notes
Verify the specific suffix 'BWM' corresponds to the wide SOIC-18 package and commercial/industrial temperature grade. Confirm RoHS compliance status as some legacy Micrel variants may contain lead. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design, as variations exist within the MIC584x family.
Selection Notes
Select this component when an 8-channel sink driver with serial interface is required. It is suitable for applications needing high voltage tolerance up to 50V on the outputs. Consider the BiCMOS process for its balance of speed and drive capability. Verify that the system clock frequency falls within the specified operating limits for reliable data shifting.
Part Context
This part belongs to the MIC584x series of serial-input latched drivers. It is functionally similar to the MIC5841 but provides eight channels instead of one. The series is designed for driving inductive or resistive loads in harsh environments. It serves as a bridge between low-voltage digital logic and higher-voltage peripheral devices.
Replacement Considerations
The MIC5842YWM is a comparable variant within the same product family offering identical functional characteristics. Users should verify package compatibility and ensure the replacement meets the specific voltage and current requirements of the original design.
