Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm package integrity and pin alignment against the 20-QSOP specification. Validate electrical parameters against datasheet limits before integration. Ensure compliance with RoHS and REACH environmental standards. Cross-reference manufacturer part numbers to avoid counterfeit substitutions.

Selection Notes

Select this component for designs requiring octal storage with three-state isolation. Consider the 2V to 3.6V operating range for low-voltage logic compatibility. Evaluate the 13ns delay for high-speed timing requirements. Assess thermal management needs within the -40°C to 85°C operational window. Compare against alternative series for specific interface or speed constraints.
