Overview
The MIC5841BV is an obsolete 8-bit serial-input latched driver fabricated using BiCMOS technology. It functions as a Serial-In Parallel-Out (SIPO) peripheral power driver with sink output current capability. The device integrates an eight-bit CMOS shift register and latches, housed in a 20-pin Plastic Quad Flat Package No-Lead (PLCC) or LCC-20 package. It operates within a temperature range of -40 °C to 85 °C and includes transient protection.
Feature Summary
- Integrates an 8-bit serial input shift register with parallel latched outputs for peripheral power driving applications
- Utilizes BiCMOS fabrication technology to support high-current sink capabilities
- Includes built-in transient protection for enhanced reliability in peripheral circuits
Applications
- Peripheral power driver applications requiring serial-to-parallel conversion
- Systems utilizing BiCMOS technology for load driving
- Industrial control interfaces needing latched output states
Procurement Notes
Verify the obsolete status of the MIC5841BV before procurement planning. Confirm RoHS compliance requirements, as this specific part number may not meet current environmental standards. Ensure compatibility with existing 20-pin PLCC/LCC footprints during design validation. Cross-reference official Microchip documentation for final electrical specifications and handling instructions.
Selection Notes
Select this component only if legacy 20-pin PLCC packaging is mandatory for the design. Evaluate the availability of the recommended replacement, MIC5841YV, which offers RoHS compliance. Consider pinout compatibility and thermal performance differences when transitioning from the obsolete BiCMOS version to newer alternatives.
Part Context
The MIC5841 series belongs to Microchip's family of 8-bit serial-input latched drivers. These devices are designed for driving peripheral loads via serial data inputs. The BV suffix typically denotes a specific package variant, often associated with older manufacturing runs or leaded compositions, distinguishing it from modern RoHS-compliant equivalents like the YV suffix.
Replacement Considerations
Microchip officially lists the MIC5841YV as the replacement for the MIC5841BV. The MIC5841YV provides RoHS compliance while maintaining functional equivalence. Verify package dimensions and pin assignments to ensure mechanical compatibility during upgrade.
