"The MSM82C59A-2 is a programmable interrupt for use in MSM80C85AH and MSM80C86A10/88A-10 microcomputer systems.
Based on CMOS silicon gate technology, this device features an extremely low standby current
of 100mA (max.) in chip non-selective status. During interrupt control status, the power
consumption is very low with only 5 mA (max.) being required.
Internally, the MSM82C59A-2 can control priority interrupts up to 8 levels, and can be
expanded up to 64 levels by cascade connection of a number of devices.

Features:

• Silicon gate CMOS technology for high speed and low power consumption
• 3 V to 6 V single power supply
• MSM80C85AH system compatibility (MAX5 MHz)
• MSM80C86A-10/88A-10 system compatibility (MAX8 MHz)
• 8-level priority interrupt control
• Interrupt levels expandable up to 64 levels
• Programmable interrupt mode
• Maskable interrupt
• Automatically generated CALL code (85 mode)
• TTL compatible
