DS0026H/883

Overview

The DS0026H/883 is a low-cost monolithic high-speed two-phase MOS clock driver and interface circuit manufactured by Rochester Electronics. It features a unique circuit design providing very high speed performance. The component is housed in an 8-pin TO-99 metal can package, classified as a dual-marked device (7800802GA). It functions as a clock fanout buffer with a 1:1 distribution ratio, supporting frequencies up to 10 MHz.

Feature Summary

• Provides high-speed two-phase clock driving capabilities
• Utilizes a unique circuit design for enhanced speed performance
• Functions as a clock fanout buffer with 1:1 distribution
• Encapsulated in a durable TO-99 metal can package

Applications

• High-speed clock distribution systems
• Two-phase clock generation interfaces
• Military and aerospace electronic assemblies requiring radiation-hardened or hermetic packages

Procurement Notes

Verify the specific lot code and date code against project requirements, as Rochester Electronics sources re-manufactured components. Confirm the presence of the dual marking (7800802GA) on the physical unit to ensure authenticity. Request full test data sheets and reliability reports from the supplier prior to purchase to validate performance consistency with original specifications.

Selection Notes

Select this component when a hermetic TO-99 package is required for environmental protection or radiation hardness. It is suitable for applications needing precise two-phase clock signals with minimal skew. Ensure the system operates within the specified frequency range of up to 10 MHz. Consider the lead time associated with specialized re-manufactured parts compared to standard commercial inventory.

Part Context

Rochester Electronics specializes in extending the lifecycle of critical semiconductors. They provide authorized re-manufacturing of obsolete parts, ensuring supply continuity for legacy systems. The DS0026H/883 represents their capability to produce high-reliability clock drivers using original designs, maintaining compatibility with existing military and industrial standards.

Replacement Considerations

No direct public substitute part numbers are documented for this specific dual-marked variant. Users should verify pin-out and electrical compatibility if considering alternative clock buffers from other manufacturers.
