Technical Details & Description

What this interrupt controller does on the bus

The P8259A-2 is a programmable interrupt controller designed to manage interrupt requests in x86 and similar microprocessor systems. It handles up to eight interrupt inputs, prioritizes them, and vectors the CPU to the appropriate service routine. The 28-pin DIP package (28-DIP) is through-hole, intended for socketed or soldered mounting on a PCB. That limits it to indoor, climate-controlled equipment — office automation, telecom racks, or benchtop test gear.

This part is RoHS non-compliant, so verify your assembly line's solder process and any regional RoHS exemptions before committing to a production run.

The 28-DIP package is a standard dual-in-line footprint.

Frequently asked questions

What are the equivalent parts to P8259A-2?

The P29C53AC is a peer controller in a similar Bulk package with a 4.75V supply, but it is not a direct pin-for-pin replacement. Verify compatibility against your specific socket and bus timing before substituting.

Is P8259A-2 RoHS compliant?

No, the P8259A-2 is listed as RoHS non-compliant. Confirm your assembly process and any applicable exemptions before ordering for production.
