Procurement Notes
Verify the specific package variant and date code against project requirements. Confirm that the lead-free status and RoHS compliance meet regulatory standards for the intended deployment region. Ensure compatibility with existing PCB footprints and thermal management solutions before finalizing procurement orders.
Selection Notes
Select this component when a quad differential driver is required for RS-422 networks. Consider the wide temperature range if the application involves outdoor or uncontrolled environments. Verify pinout compatibility with legacy designs using the original Texas Instruments DS26LS33 specifications to ensure seamless integration without redesigning the board layout.
Part Context
Rochester Electronics specializes in sustaining end-of-life semiconductor products. This part is typically sourced from authorized wafer banks or licensed manufacturing partners. It serves as a replacement for obsolete original manufacturer parts, maintaining functional equivalence while addressing supply chain constraints for critical legacy systems.
Replacement Considerations
Direct replacements include the Texas Instruments DS26LS33 series. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
