• Provides parallel error detection and correction capabilities for 32-bit data paths
• Utilizes Advanced Schottky (AS) logic technology for high-speed performance
• Designed for industrial temperature operation ranges

Applications

• High-speed data bus error monitoring systems
• Memory subsystem integrity verification
• Digital communication interface protection circuits

Procurement Notes

Verify the exact package pinout and electrical specifications against the official Rochester Electronics datasheet before integration. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process. Ensure the source is an authorized distributor to guarantee part authenticity and traceability.

Selection Notes

Select this component when 32-bit parallel error handling is required in AS-logic speed classes. Compare propagation delays and output drive currents against system timing budgets. Verify that the FN package dimensions align with the target PCB footprint constraints and assembly capabilities.

Part Context

Rochester Electronics specializes in lifecycle management for obsolete and hard-to-find semiconductors. This part belongs to the 74AS family, known for faster switching speeds compared to standard TTL. The 74AS632 serves a niche role in error correction, distinct from standard logic gates or memory devices.

Replacement Considerations

Direct cross-references may be limited due to the specialized nature of the 32-bit error correction function. Verify compatibility with existing 74AS-series designs. Consult manufacturer substitution guides for equivalent functionality if the original part is unavailable.
