• Generates continuous signals for system synchronization
• Supports high-frequency operation up to 40MHz

Buffers, Drivers, Receivers, Transceivers Applications

• Futurebus+ arbitration controller implementations
• High-speed digital bus management systems
• Continuous signal generation for peripheral interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MPR indicates the tape-and-reel packaging variant when sourcing. Confirm the manufacturer origin is National Semiconductor or its successor entity Texas Instruments. Ensure the component matches the CQFP68 physical footprint requirements for your PCB design before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a dedicated hardware solution for bus arbitration is required rather than software-based control. The 40MHz operational speed makes it suitable for demanding data throughput applications. Consider the CQFP68 package constraints during layout planning to ensure adequate thermal dissipation and pin accessibility.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the National Semiconductor logic IC family focused on bus interface and arbitration controllers. It serves as a specialized integrated circuit for managing concurrent access requests in multi-master bus architectures, distinct from standard buffer or driver components.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official datasheets for direct cross-reference equivalents. Verify pin compatibility and electrical specifications before substituting with other Futurebus+ compatible arbiters from different manufacturers.
