Display Drivers Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by Texas Instruments. Verification of availability should focus on surplus or secondary market sources rather than direct production channels. Confirm the exact datasheet specifications before integration, as legacy parts may have limited long-term support or replacement options available from the manufacturer.

Display Drivers Selection Notes

Select this part only for maintenance of existing designs requiring the specific COP472-3 architecture. Evaluate alternative modern LCD controllers if new product development is intended, given the obsolete status. Ensure design compatibility with the 20-SOIC package and verify that the low power dissipation requirements align with the system's thermal constraints.

Display Drivers Part Context

The COP472 series represents a line of liquid crystal display drivers designed for simple to complex display segments. The COP472WM-3 variant specifically targets applications needing a dedicated controller for LCD panels. It integrates necessary driving logic within a standard surface-mount package, facilitating integration into embedded systems requiring visual output.

Display Drivers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source data due to the obsolete status. Designers should consult Texas Instruments for recommended upgrades or equivalent functional replacements suitable for new implementations.
