54F241FMQB

Overview

The 54F241FMQB is a military-grade buffer and driver integrated circuit manufactured by National Semiconductor. It features two non-inverting elements, each providing four-bit wide tri-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 20-lead Ceramic Flat Pack (CFLATPACK) package designed for high reliability applications.

Feature Summary

• Provides dual independent four-bit buffering channels with non-inverting logic functionality
• Integrates tri-state output capability allowing multiple drivers to share bus lines without interference
• Constructed using ceramic flat pack packaging to ensure durability in harsh environments

Applications

• Military aerospace systems requiring radiation-hardened or high-reliability logic components
• Avionics data bus interfaces utilizing tri-state signaling protocols
• Industrial control systems operating under extreme temperature conditions

Procurement Notes

Verify the specific suffix FMQB corresponds to the ceramic flat pack variant when sourcing. Confirm that the component meets all required military specifications and environmental ratings for your intended deployment. Ensure compatibility with existing board layouts due to the specific pinout of the 20-CFLATPACK housing.

Selection Notes

Select this component when high-reliability buffering is required for critical digital signals. The tri-state feature is essential for bus-oriented architectures where signal isolation is necessary. Consider the ceramic package for superior thermal and mechanical stability compared to plastic alternatives in demanding operational scenarios.

Part Context

This part belongs to the 54F series of logic devices, which are characterized by their military-grade qualification standards. The 54F series typically offers performance comparable to standard commercial logic but with enhanced testing and reliability guarantees suitable for defense and space applications.

Replacement Considerations

Direct replacements may include other 54F241 variants from Texas Instruments or National Semiconductor. Verify pin compatibility and electrical characteristics before substituting. Cross-reference with SN54F241 equivalents if available.
