JD54LS241BRA

Overview

The JD54LS241BRA is an octal tri-state buffer and line driver manufactured by National Semiconductor. It features two independent four-bit buffers with separate output enable controls, allowing for flexible bus orientation management. The device operates at a standard 5 V supply voltage and provides true output polarity. Designed for high-speed digital applications, it supports bidirectional data transmission on system buses while maintaining low power consumption characteristic of the LS logic family.

Feature Summary

• Octal configuration providing eight independent buffered outputs
• Tri-state capability enabling effective bus isolation and sharing
• Dual control inputs for independent direction management
• True output polarity ensuring signal integrity

Applications

• Bus-oriented memory and I/O systems
• Clock drivers and timing circuits
• Bidirectional data transceivers
• Line driving for long cable runs

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are now managed by Texas Instruments or Rochester Electronics. Confirm the package type matches the required DIP or CDIP form factor. Ensure the revision level aligns with legacy design requirements. Check for RoHS compliance status if environmental regulations apply to the specific production batch.

Selection Notes

Select this component when an octal buffer with tri-state control is required for bus architectures. Compare propagation delay specifications against system clock speeds. Evaluate power dissipation limits relative to thermal constraints. Consider pin compatibility with existing PCB layouts before finalizing the part number selection.

Part Context

This part belongs to the 54/74LS series of logic devices, widely used in military and commercial applications. The 'J' suffix typically denotes a ceramic dual in-line package. As a legacy component, it serves in maintenance and retrofit scenarios for older digital systems requiring robust bus driving capabilities.

Replacement Considerations

Direct substitutes include SN54LS241 variants from other manufacturers. Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with Texas Instruments equivalents for updated sourcing options.
