MIC5842BV

Overview

The MIC5842BV is an 8-bit serial-input latched driver manufactured by Microchip Technology. It utilizes BiCMOS logic technology to provide high-current sinking capabilities for peripheral loads. The device accepts serial data input and shifts it through an internal 8-stage register, latching the output state on a clock edge. It operates within a temperature range of -40°C to +85°C and is housed in a 20-pin PLCC package.

Feature Summary

• Serial-to-parallel conversion with internal latching mechanism
• High-current sink outputs suitable for driving peripherals
• BiCMOS construction for robust performance

Applications

• Peripheral driver circuits
• LED matrix displays
• Relay control interfaces

Procurement Notes

Verify the specific suffix 'BV' corresponds to the 20-pin PLCC package variant. Confirm RoHS compliance status as some sources indicate replacement by MIC5842YV. Ensure the supplier provides official Microchip documentation to validate the part number against obsolete lists.

Selection Notes

Select this component when an 8-bit shift register with latched outputs is required in a PLCC package. Consider the MIC5842YV if a lead-free or alternative package option is needed. Verify current sourcing availability due to potential obsolescence status indicated by distributor listings.

Part Context

This component belongs to the MIC5841/5842 family of serial-input latched drivers. The MIC5842 variant specifically offers 8 bits of storage. It is designed for applications requiring direct interface between low-voltage logic controllers and higher-current loads without additional buffering components.

Replacement Considerations

Public sources indicate the MIC5842BV may be obsolete and replaced by the MIC5842YV.
