Intersil 82C59A Datasheet
The 82C59A is a high‑performance CMOS priority interrupt controller designed to relieve the CPU from polling in multilevel priority systems. It supports 5 MHz, 8 MHz and 12.5 MHz versions and is pin‑compatible with the NMOS 8259A, making it suitable for a range of microprocessors such as the 8080/85, 8086/88 and 80286 families.
The device operates from a single 5 V supply, offers low static power consumption, and is available in commercial, industrial and military temperature ranges. It can handle up to eight vectored interrupt sources and can be cascaded to manage up to 64 sources without additional circuitry.
