5962-9471801QRA

Overview

The Texas Instruments 5962-9471801QRA is a military-grade octal buffer and driver belonging to the SN54ABT541 series. It features BICMOS technology with three-state outputs, housed in a 20-pin CDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55°C to +125°C. Key electrical parameters include a propagation delay of 10 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA.

Feature Summary

• Octal configuration providing eight independent buffering channels for high-density signal routing
• Three-state output capability enabling direct connection to bus structures without external transceivers
• BICMOS construction delivering high-speed performance with low power consumption characteristics

Applications

• Military aerospace systems requiring radiation-hardened or high-reliability logic components
• High-speed data bus architectures utilizing parallel data transfer protocols
• Industrial control systems operating under extreme environmental temperature conditions

Procurement Notes

Verify component authenticity through authorized distribution channels due to military specification requirements. Confirm package integrity and lead marking consistency against official datasheet specifications. Ensure storage conditions maintain moisture sensitivity levels appropriate for ceramic dual in-line packages. Request full traceability documentation including lot codes and manufacturing origin records for quality assurance compliance.

Selection Notes

Select this component when designing systems requiring octal buffering with simultaneous enable/disable functionality. Consider the CDIP package constraints for through-hole mounting versus surface area availability. Evaluate the BICMOS technology benefits regarding switching speed versus static power dissipation compared to standard CMOS alternatives. Verify voltage compatibility with existing system rails before integration into complex logic networks.

Part Context

This part number represents the military variant of the commercial SN54ABT541 octal buffer. It shares functional equivalence with the SN74ABT541 but meets stricter reliability standards defined by Department of Defense specifications. The designation indicates a specific screening level and testing protocol distinct from commercial grade equivalents.

Replacement Considerations

SN54ABT541J is the commercial equivalent offering identical logical functionality. SN54ABT541FC is available as a flat pack alternative with compatible pinout. Verify that substitute parts meet the required military temperature and screening standards if applicable.
