Procurement Notes

Verify the obsolete status and discontinuance notice prior to procurement. Confirm that the PDIP-28 package aligns with existing PCB footprints. Ensure compliance with RoHS non-compliance requirements if environmental regulations apply. Validate that the 4.5 V to 5.5 V supply range matches system power rails. Check for available replacement options due to end-of-life status.

Selection Notes

Select this component when asynchronous FIFO functionality with 9-bit width is required. Consider the 25 ns access time for speed matching with host processors. Evaluate the 28-pin DIP package constraints for mechanical integration. Assess the 120 mA current draw against thermal management capabilities. Verify compatibility with 5 V logic levels for reliable signal interfacing.
