FIFOs Memory Procurement Notes

Verify that the supplier is an authorized distributor such as Rochester Electronics to ensure component authenticity. Confirm the specific suffix 'ASDMQB' matches design requirements, as variations may exist. Review the official datasheet for electrical characteristics and operating conditions before integration.

FIFOs Memory Selection Notes

Select this component when a legacy National Semiconductor FIFO solution is required for existing designs. Consider pin compatibility and interface timing specifications against current system requirements. Evaluate alternative modern FIFOs if new design constraints allow for updated packaging or performance features.

FIFOs Memory Part Context

Rochester Electronics distributes discontinued National Semiconductor products, including the 9403 series. The 9403ASDMQB represents a specific variant within this family, maintaining original functional specifications while being sourced through Rochester's supply chain for continued availability.

FIFOs Memory Replacement Considerations

The 9403ADMQB is listed as a similar component with identical FIFO description and manufacturer. Verify pinout and electrical equivalence before substitution.
