JD54F244SSA

Overview

The JD54F244SSA is a military-grade octal buffer and line driver manufactured by National Semiconductor. It features two non-inverting elements, each handling four bits with tri-state outputs. The device utilizes a 20-pin Ceramic Flat Pack (CFP) package. As a space-level logic component, it adheres to JM38510/32403SSA specifications. The part is lead-free and RoHS compliant, designed for high-reliability applications requiring robust signal buffering in harsh environments.

Feature Summary

• Military-grade construction with environmental and burn-in processing
• Octal configuration with tri-state output capability
• Non-inverting logic function for signal buffering

Applications

• Space-level logic systems
• Military electronic equipment
• High-reliability bus drivers

Procurement Notes

Verify the specific suffix SSA confirms the 20-pin CFP package and JM38510/32403SSA compliance. Confirm RoHS status and lead-free certification if required for assembly processes. Ensure the supplier provides traceability documentation consistent with military grade standards. Check for any additional environmental qualification markings on the component body.

Selection Notes

Select this component when military reliability and space-level qualification are mandatory. The octal structure suits wide data buses. Tri-state outputs allow multiple drivers on shared lines. The ceramic package offers superior thermal and mechanical stability compared to plastic alternatives. Verify voltage levels match system requirements before integration.

Part Context

This part belongs to the 54F244 family of octal buffers. It shares functional similarities with commercial variants but meets stricter military specifications. The JD prefix indicates a specific military or space-qualified version. It serves as a critical interface component for driving loads in demanding operational conditions.

Replacement Considerations

Direct substitutes include other 54F244 variants with compatible pinouts. Verify that replacement parts meet the same JM38510/32403SSA standard. Commercial equivalents lack the required environmental processing. Ensure package dimensions match the existing footprint.
