DM9348W/883

Parity Generators And Checkers Overview

The DM9348W/883 is a high-reliability parity generator and checker manufactured by National Semiconductor. It features a 12-bit input capability within a single-element die design. The device operates in an asynchronous mode and is housed in a 16-pin ceramic flatpack (CFP-16) package. It is designed for military and aerospace applications, supporting a wide operating temperature range from -55 °C to 125 °C. The component is RoHS non-compliant and utilizes a 5 V power supply with a maximum current consumption of 5.5 mA.

Parity Generators And Checkers Procurement Notes

Verify the specific revision level and lot traceability documentation upon procurement. Confirm that the RoHS non-compliant status aligns with your project's regulatory requirements. Ensure the ceramic flatpack package integrity is inspected for any shipping damage prior to integration into sensitive military or aerospace assemblies.

Parity Generators And Checkers Selection Notes

Select this component when a 12-bit parity solution is required in a ruggedized form factor. The ceramic flatpack package offers superior thermal and mechanical stability compared to plastic alternatives. Consider the 5 V supply requirement and 5.5 mA current draw during power budgeting for the target system architecture.

Parity Generators And Checkers Part Context

This part belongs to the DM93 series of high-reliability logic devices produced by National Semiconductor. The /883 suffix indicates compliance with MIL-PRF-38534 standards for hybrid microcircuits. It is distinct from standard commercial logic parts due to its specialized packaging and rigorous manufacturing controls for defense applications.

Parity Generators And Checkers Replacement Considerations

Direct substitutes must match the 12-bit parity function and CFP-16 package. Verify equivalent MIL-PRF-38534 qualification levels. Cross-reference with other DM93 series variants if pinout compatibility is critical.
