Description and Introduction

CMOS Priority Interrupt Controller The IS82C59A-12 is a programmable interrupt controller (PIC) manufactured by **INTERSIL**.  

### **Specifications:**  
- **Part Number:** IS82C59A-12  
- **Manufacturer:** INTERSIL  
- **Type:** CMOS Priority Interrupt Controller  
- **Operating Voltage:** 5V  
- **Speed:** 12 MHz  
- **Package:** 28-pin DIP, PLCC, or other standard packages  
- **Compatibility:** Fully compatible with Intel 8259A  
- **Interrupts:** 8-level priority interrupt control  
- **Cascading Support:** Can be cascaded to handle up to 64 interrupt levels  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Descriptions:**  
The IS82C59A-12 is a high-performance, CMOS version of the industry-standard 8259A interrupt controller. It manages interrupt requests from peripheral devices and prioritizes them for the CPU. It is widely used in microprocessor-based systems to enhance interrupt handling efficiency.  

### **Features:**  
- **Fully Static CMOS Design** – Low power consumption  
- **Programmable Interrupt Modes** – Supports various priority schemes  
- **Edge and Level Triggered Interrupts** – Configurable input modes  
- **Automatic EOI Mode** – Reduces software overhead  
- **Buffered Mode Support** – For large system configurations  
- **Single +5V Power Supply** – Standard power requirement  
- **Fully TTL Compatible** – Ensures compatibility with TTL logic levels  

This IC is commonly used in embedded systems, industrial controls, and computing applications requiring efficient interrupt management.
