Memory IC Procurement Notes

Verify the specific suffix JDM against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure that the procurement channel provides traceability documentation required for military or aerospace components. Confirm that the ceramic DIP package matches the target PCB footprint and that the operating temperature range meets the system's environmental requirements before finalizing the order.

Memory IC Selection Notes

Select this component when radiation tolerance and wide temperature stability are critical. Compare against other SMJ series variants to ensure bit organization and access times meet system timing constraints. Verify that the 16-pin DIP form factor aligns with existing board layouts. Consider power consumption and interface voltage levels relative to the host processor or controller in the design.

Memory IC Part Context

This part belongs to Texas Instruments' SMJ family of radiation-hardened memory devices. These components are engineered for reliability in space and defense applications where standard commercial parts would fail due to ionizing radiation or extreme thermal conditions. The SMJ series typically offers higher cost but significantly greater longevity and data integrity in hostile environments compared to commercial grade equivalents.

Memory IC Replacement Considerations

Check for direct cross-reference numbers within the SMJ series. Verify if alternative radiation-hardened SRAMs from other manufacturers offer compatible pinouts and timing parameters.
