25LS22FM/B

Overview

The AM25LS22FM/B is an 8-bit serial/parallel shift register manufactured by Rochester Electronics, LLC. It utilizes advanced low-power Schottky (LS) technology to ensure high-speed operation with reduced power consumption. The device functions as a parallel-in, parallel-out element with right-direction shifting capability and true outputs. It features an 8-bit parallel multiplexed I/O structure, making it suitable for digital data storage and transfer applications in logic circuits.

Feature Summary

• Fabricated using advanced low-power Schottky technology for efficient performance
• Provides 8-bit parallel multiplexed input/output capabilities
• Operates as a parallel-in, parallel-out shift element with true output states

Applications

• Digital signal processing systems requiring data shifting
• Parallel-to-serial or serial-to-parallel data conversion interfaces
• General-purpose logic circuitry for temporary data storage

Procurement Notes

Verify the manufacturer designation as Rochester Electronics, LLC, which acts as an authorized source for lifecycle extension components. Confirm the specific suffix FM/B matches the required package and temperature grade. Request original factory documentation to validate authenticity, as this component represents a specialized logic element rather than a standard commodity item.

Selection Notes

Select this component when an 8-bit LS-series shift register with parallel I/O is required. Ensure compatibility with low-power Schottky logic families within the system design. Verify that the true output configuration aligns with downstream logic requirements. Consider the physical package constraints associated with the FM/B suffix during PCB layout planning.

Part Context

Rochester Electronics specializes in providing lifecycle management solutions for obsolete and hard-to-find semiconductors. This part belongs to the AM25LS22 family of logic shift elements. The company ensures supply continuity for critical industrial and aerospace applications where original manufacturers may have discontinued production.

Replacement Considerations

Direct substitutes include other AM25LS22 variants from different manufacturers if pin-compatible. Verify electrical characteristics match the LS series specifications. No alternative part numbers are explicitly confirmed in public documentation for direct replacement without schematic review.
