Display Drivers Procurement Notes

Verify current availability status as this component is marked as obsolete or end-of-life by the manufacturer. Sourcing may require checking authorized distributors for remaining stock or alternative suppliers like Rochester Electronics. Confirm RoHS compliance details and moisture sensitivity level (MSL 4) prior to procurement to ensure storage and handling requirements are met for surface mount assembly processes.

Display Drivers Selection Notes

Select this component when a dedicated LCD driver with serial interface capability is required for segment displays. Ensure the design accommodates the 64-LQFP package footprint and the specified voltage range. Consider the operating temperature limits for environmental suitability. Verify that the segment count requirements align with the supported 53 or 104 segment configurations before finalizing the bill of materials.

Display Drivers Part Context

This part belongs to the LC75821 series of LCD drivers from onsemi. It falls under the subcategory of Driver ICs within the Power Management (PMIC) classification. The product is distinct from other series like LC75808 or LC75832 due to its specific segment support and package type. It serves as a specialized solution for driving static or multiplexed LCD segments in embedded applications.

Display Drivers Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation.
