Procurement Notes
This component is officially classified as obsolete and has been discontinued by the manufacturer. Verify end-of-life status before design implementation. Sourcing may be limited to surplus or secondary markets. Confirm compatibility with existing designs if considering replacement strategies due to unavailability through standard distribution channels.
Selection Notes
Select this component only for legacy system maintenance where specific pinout and electrical characteristics are required. Evaluate alternative modern equivalents if designing new hardware, as availability is restricted. Ensure power supply rails match the 5.5V to 16.8V operational range and verify thermal management requirements for the TQFP-48 package.
Part Context
The TSL1018 belongs to the TSL1018 series of LCD drivers from STMicroelectronics. It is part of a family of components designed for thin-film transistor liquid crystal displays. The 'IF' suffix indicates the specific tape and reel packaging variant within this product line.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
