IS82C59A-12R2413 REEL

Specialized Overview

The IS82C59A-12R2413 is an interrupt controller compatible with the Intel 8080, 8085, 80C86, and 80C88 architectures. Manufactured by Harris Corporation, this CMOS device manages up to eight external interrupt requests. It operates within a voltage range of 4.5V to 5.5V and supports data bus widths of 8 bits. The component is supplied in a tape and reel packaging format, designated by the suffix 'REEL', suitable for automated surface-mount assembly processes.

Specialized Feature Summary

• Supports cascading configurations to expand interrupt handling capabilities beyond the primary eight channels
• Features programmable mask registers allowing individual control over interrupt request lines
• Includes automatic End-of-Interrupt (EOI) command logic for simplified software integration

Specialized Applications

• Intel 8086/8088-based personal computer systems
• Industrial control units requiring deterministic interrupt latency
• Embedded processing modules utilizing 8-bit microprocessor architectures

Specialized Procurement Notes

Verify the specific suffix 'R2413' against official Harris or successor manufacturer documentation to confirm exact electrical grade and temperature range specifications. Ensure the reel quantity matches production requirements and that the CMOS technology aligns with the target system's power constraints. Confirm RoHS compliance status as original Harris components may predate modern environmental directives.

Specialized Selection Notes

Select this component when designing systems requiring direct compatibility with legacy Intel 8080/8085 interrupt structures. Consider the CMOS construction for lower power consumption compared to earlier TTL equivalents. Evaluate the need for the specific reel packaging if high-volume automated placement is required versus bulk DIP alternatives.

Specialized Part Context

This part belongs to the 82C59A family of Advanced Programmable Interrupt Controllers (APIC). Harris Corporation was a primary semiconductor supplier for these controllers before industry consolidation. The 'IS' prefix typically denotes industrial temperature range variants within the broader 82C59A product line.

Specialized Replacement Considerations

Direct replacements include the CP82C59A from Renesas or the MC68HC000 series interrupt controllers from NXP/Freescale. Verify pinout compatibility and register set alignment before substitution to ensure seamless integration into existing firmware drivers.
