SNJ54LS241FK

Overview

The SNJ54LS241FK is a military-grade octal buffer and line driver from Texas Instruments' LS series. It features two independent four-bit drivers with true outputs and three-state capabilities. The device utilizes a 20-pin ceramic LCC (LCC-20) package, designed for high reliability in harsh environments. It operates within an extended temperature range of -55°C to 125°C. The component supports unidirectional data flow with dual output enable controls, ensuring precise bus management in complex digital systems.

Feature Summary

• Provides octal buffering with three-state outputs for efficient bus sharing
• Features dual independent four-bit drivers with true output polarity
• Constructed in a hermetically sealed ceramic package for environmental durability
• Supports extended industrial and military temperature operation ranges

Applications

• Military avionics bus interface circuits
• High-reliability telecommunications equipment
• Harsh environment data acquisition systems
• Spacecraft onboard computer memory addressing

Procurement Notes

Verify the specific suffix FK indicates the ceramic LCC-20 package configuration. Confirm the manufacturer source is Texas Instruments or an authorized distributor. Ensure the component meets military grade specifications if required for the application. Check for lead-free compliance status as older military parts may differ. Validate the date code against current inventory standards.

Selection Notes

Select this component when military-grade reliability and ceramic packaging are mandatory. Compare against SN54LS241 variants with different package types like CDIP or CFP based on board space constraints. Consider power consumption differences between LS and ALS series if thermal management is critical. Ensure voltage levels match the system logic family requirements.

Part Context

This part belongs to the SNx4LS24x family of octal buffers and line drivers. It shares functional compatibility with other LS series devices but differs in packaging and grade. The ceramic construction distinguishes it from plastic packaged commercial versions. It serves as a robust solution for applications requiring high noise immunity and physical protection.

Replacement Considerations

SNJ54LS241J: Ceramic DIP variant. SNJ54LS241W: Ceramic flatpack variant. SN54LS241FK: Commercial grade equivalent.
