54LS96/BEA

Overview

The 54LS96/BEA is a 5-bit serial-in, parallel-out shift register manufactured by Rochester Electronics. It operates within the military temperature range of -55°C to 125°C. The device features a master-slave architecture with independent clock inputs for data storage and shifting operations. It supports standard TTL logic levels and is designed for high-reliability applications requiring robust performance under extreme environmental conditions.

Feature Summary

• Provides 5-bit serial-to-parallel data conversion capability
• Operates reliably across the full military temperature spectrum
• Features independent clocking for storage and shift functions

Applications

• Military communication systems requiring reliable data transmission
• Avionics control units needing serial data processing
• Industrial automation controllers operating in harsh environments

Procurement Notes

Verify the specific suffix BEA against the original manufacturer datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the component meets MIL-PRF-38535 Class Q standards if required for your application. Confirm that the military temperature rating aligns with your system's operational environment constraints before finalizing procurement.

Selection Notes

Select this component when a 5-bit shift register is needed for military-grade reliability. Consider its independent clock inputs if separate control over data loading and shifting is necessary. Evaluate the package type compatibility with your PCB layout. Verify that the LS series speed and power consumption meet your system's overall performance budget compared to other available logic families.

Part Context

Rochester Electronics specializes in manufacturing legacy and obsolete semiconductor components using original dies or recreated IP. The 54LS96/BEA falls under their logic product line, specifically shift registers. These parts are often sourced from original manufacturers or recreated to maintain supply chain continuity for critical defense and aerospace applications where newer alternatives may not be suitable.

Replacement Considerations

Direct substitutes include other 54LS96 variants from different manufacturers, provided they meet the same military temperature and electrical specifications. Verify pin compatibility and logical function equivalence before substitution. Cross-reference with SN54LS96 datasheets to ensure functional parity in your specific circuit configuration.
