54LS395A/BEA

Overview

The 54LS395A/BEA is a high-speed silicon-gate LS Logic device manufactured by Rochester Electronics. It functions as an 8-bit serial-in or parallel-in, serial-out or parallel-out shift register with three-state outputs. The component utilizes standard LS logic electrical characteristics and is designed for military-grade reliability standards. It features independent clock inputs for serial and parallel loading operations, allowing flexible data handling in digital systems requiring robust signal shifting and storage capabilities.

Feature Summary

• Supports both serial input and parallel input data loading modes
• Provides three-state outputs for bus-driven applications
• Features separate clock controls for serial and parallel operations

Applications

• Military communication systems requiring reliable data shifting
• Industrial control interfaces utilizing LS logic levels
• Test equipment needing serial-to-parallel conversion

Procurement Notes

Verify the specific suffix BEA against official manufacturer documentation to confirm package type and temperature range specifications. Ensure that the procurement channel provides traceability to the original manufacturer or authorized distributor. Confirm RoHS compliance status if required by the end application, as military variants may differ from commercial equivalents. Request detailed datasheets to validate pinout compatibility before integration.

Selection Notes

Select this component when designing systems that require high-reliability shift registers operating under strict military environmental conditions. It is suitable for applications demanding precise timing control via independent clock inputs. Consider the three-state output capability if the design requires sharing a common data bus with other logic devices. Verify voltage supply requirements match the system's power distribution network.
