Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm lead finish specifications match design requirements. Ensure proper handling procedures are followed due to surface mount packaging. Validate RoHS compliance status against current project standards before integration into final assemblies.

Selection Notes

Select this component for designs requiring high-speed data latching with differential signaling capabilities. Consider the industrial temperature range and voltage flexibility when evaluating system constraints. Verify interface compatibility with existing CML or PECL drivers to ensure signal integrity across the operating bandwidth.

Part Context

This device belongs to the SuperLite family of high-speed CML logic components. The family emphasizes small packaging solutions and wide voltage operation ranges. These characteristics support compact, high-performance digital designs requiring reliable data storage and transfer at elevated frequencies.

Replacement Considerations

Check for direct equivalents within the same product family. Evaluate alternative latch configurations if pinout compatibility is required. Review datasheet specifications to ensure functional parity regarding speed and voltage tolerances.
