Product Summary

The IS82C59A is a high performance CMOS Priority Interrupt Controller manufactured using an advanced 2mm CMOS process. The IS82C59A is designed to relieve the system CPU from the task of polling in a multilevel priority system. The IS82C59A can handle up to eight vectored priority interrupting sources and is cascadable to 64 without additional circuitry. Individual interrupting sources can be masked or prioritized to allow custom system configuration. Two modes of operation make the IS82C59A compatible with both 8080/85 and 80C86/88/286 formats.
