5962-9074901MRA

Overview

The Texas Instruments 5962-9074901MRA is a military-grade octal buffer and line driver based on the SN54BCT541 architecture. It features eight non-inverting outputs with three-state capability, housed in a 20-pin Ceramic Dual In-Line Package (CDIP). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -55°C to +125°C. Designed for high-speed digital signal buffering, it utilizes BCT technology to ensure compatibility with TTL input levels while providing CMOS performance characteristics.

Feature Summary

• Octal configuration providing eight independent non-inverting buffer channels
• Three-state output control enabling efficient bus-oriented architectures
• Military qualification ensuring reliability in extreme environmental conditions
• BCT technology combining bipolar speed with CMOS power efficiency

Applications

• Military avionics signal distribution systems
• High-reliability data bus buffering applications
• Spacecraft telemetry and command logic interfaces
• Harsh environment industrial control system drivers

Procurement Notes

Verify that the specific suffix MRA corresponds to the required ceramic package and military grade specification. Confirm that the component meets all necessary environmental testing standards for the intended deployment. Ensure that the source documentation explicitly lists this part number as an active production item or qualified replacement. Check for any specific handling requirements associated with ceramic dual in-line packages during assembly.

Selection Notes

Select this component when eight buffered channels with tri-state isolation are required for critical systems. The SN54 family designation indicates suitability for environments requiring wide temperature stability. Consider the CDIP package constraints regarding board space and thermal management. Verify that the input logic levels match the driving circuitry to ensure proper signal integrity without additional level shifting components.

Part Context

This part belongs to the SN54 series of logic integrated circuits manufactured by Texas Instruments. The SN54 designation signifies military-grade quality, distinguishing it from commercial SN74 variants. The underlying SN54BCT541 design provides a robust solution for buffering complex digital signals in aerospace and defense electronics where standard commercial components would fail under stress.

Replacement Considerations

Direct substitutes include other SN54BCT541 variants with compatible packaging and grade specifications. Cross-reference with SN54BCT541J or similar military-qualified equivalents if pinout compatibility is maintained. Verify that any alternative maintains the same three-state control logic and voltage operating ranges.
