54LCX245J-QML

Overview

The 54LCX245J-QML is a non-inverting transceiver designed for bidirectional data communication in digital logic circuits. It features one element with eight bits per element and tri-state outputs. The device operates at a supply voltage of 3.6V and is housed in a 20-pin ceramic DIP package (CERDIP). This component is intended for bus-oriented applications, providing high-speed data transfer capabilities within mixed-signal systems.

Feature Summary

• Non-inverting bidirectional data communication capability
• Tri-state outputs for efficient bus management
• Designed for bus-oriented applications

Applications

• Bidirectional data communication in digital logic circuits
• Bus-oriented applications requiring non-inverted output
• Mixed-signal system interfacing

Procurement Notes

Verify the specific QML qualification status and ceramic package integrity upon receipt. Confirm that the supplier provides traceability documentation consistent with National Semiconductor or Texas Instruments standards. Ensure the part matches the 20-CERDIP form factor and 3.6V operating specification to avoid integration errors in sensitive military or aerospace-grade designs.

Selection Notes

Select this component when a robust, radiation-hardened or high-reliability transceiver is required for bidirectional bus architectures. The ceramic DIP package offers superior thermal and mechanical stability compared to plastic variants. Ensure the design supports the 3.6V supply rail and requires non-inverting signal paths with tri-state control for effective bus sharing.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices, manufactured by National Semiconductor, now part of Texas Instruments. The 'QML' suffix indicates qualification under Military/Space standards, distinguishing it from commercial grade parts. It serves as a specialized variant of the standard LCX245, tailored for environments demanding higher reliability and specific packaging constraints.

Replacement Considerations

Direct substitutes include other QML-qualified LCX245 variants from Texas Instruments. Verify pin compatibility and electrical specifications before replacing. Commercial equivalents like the standard LCX245 may lack the necessary environmental qualifications for space or military applications.
