MIC5842BV-TR

Overview

The MIC5842BV-TR is an 8-bit serial-input latched driver manufactured by Microchip Technology. It features a bipolar output configuration with low-side switching capability, designed to sink up to 500mA per channel. The device utilizes a 1:8 input-to-output ratio and operates within a voltage range supporting negative supplies down to –20V. It is housed in a 20-pin PLCC (9x9) surface-mount package and is supplied in tape and reel format.

Feature Summary

• Serial input architecture for efficient data loading
• Latched output state retention without continuous clocking
• High-current bipolar Darlington sink drivers
• Robust negative supply tolerance for industrial environments

Applications

• Industrial automation control systems
• LED matrix display drivers
• Relay and solenoid actuation circuits
• Peripheral interface expansion modules

Procurement Notes

Verify the specific suffix 'BV' against the official Microchip datasheet to confirm the maximum voltage rating and operating temperature range. Confirm that the 'TR' designation indicates tape and reel packaging. Check for current production status as older revisions may be discontinued or replaced by newer equivalents.

Selection Notes

Select this component when high-current sinking capability is required for multiple loads controlled via a serial interface. Ensure the application voltage does not exceed the BV variant's limits. Consider thermal dissipation requirements due to the bipolar output structure and potential heat generation during continuous operation at maximum current ratings.

Part Context

This part belongs to the MIC5841/MIC5842 family of peripheral drivers. The MIC5842 series provides eight independent outputs controlled by a single serial input line. The BV variant specifically denotes voltage and temperature specifications distinct from other suffixes like BN or YN, which may offer different packages or environmental ratings.

Replacement Considerations

Direct substitutes include the MIC5842YN for through-hole applications. Verify pin compatibility and electrical ratings before replacing. Other variants in the MIC5842 family may require schematic adjustments if package types or voltage tolerances differ significantly.
