Overview
The AM25LS2521XM (also designated as 25LS2521/BRA) is an 8-bit identity comparator from the TTL/H/L series, manufactured by Rochester Electronics. It features inverted outputs and a cascadable architecture. The device operates within a temperature range of -55 °C to 125 °C and utilizes a 20-pin DIE package with rectangular geometry. Key electrical characteristics include series-resistor output capabilities and a single functional unit per package.
Feature Summary
- Provides 8-bit identity comparison functionality with inverted logic outputs
- Supports cascading for multi-bit expansion applications
- Operates reliably across extended industrial temperature ranges
Applications
- Digital circuit bit-level comparison operations
- Magnitude comparison in legacy TTL systems
- Data validation in industrial control environments
Procurement Notes
Verify the specific marking code on the component die against the manufacturer's dual-marking documentation. Confirm that the received part matches the 5962-8671301RA specification if military-grade compliance is required. Ensure the package type corresponds to the bare die format rather than a standard DIP housing, as physical dimensions differ significantly.
Selection Notes
Select this component when an 8-bit identity check is required within a TTL-compatible logic family. The inverted output polarity must be accounted for in downstream gate design. Consider the bare die packaging constraints during PCB layout and assembly planning. Verify thermal management requirements given the wide operating temperature span.
Part Context
Rochester Electronics specializes in sustaining obsolete semiconductor technologies. This part belongs to their extensive inventory of licensed and tested legacy devices. The company maintains production capabilities for components that are no longer actively developed by original OEMs, ensuring supply continuity for critical infrastructure.
Replacement Considerations
The 25LS2521/BRA is dual marked as 5962-8671301RA. Verify pinout compatibility before substitution. No direct cross-brand equivalents are confirmed in public documentation.
