D8259AC-2 ,Programmable Interrupt Controller - DIP-28 Package

The D8259AC-2 is a programmable interrupt controller (PIC) from NEC, designed to enhance the interrupt-handling capabilities of microprocessors by providing a prioritized interrupt environment. It is commonly used in computer systems to manage multiple interrupt requests and provide a more efficient and organized approach to handling interrupts.

This controller is compatible with Intel microprocessors and can be cascaded to accommodate up to 64 interrupt requests. Housed in a 28-pin DIP (Dual In-line Package), it is suitable for through-hole mounting on PCBs, making it ideal for embedded systems, industrial controls, and computer hardware applications that require efficient interrupt management.

• Programmable Interrupt Prioritization: Supports up to 8 priority levels, allowing flexible interrupt management based on application needs.
• Cascading Capability: Supports cascading of multiple 8259A controllers, enabling management of up to 64 interrupt lines.
• Compatibility: Designed to be compatible with Intel microprocessors, providing seamless integration with various CPUs.
• Edge and Level Triggered Modes: Configurable for edge-triggered or level-triggered interrupts, making it versatile for various applications.
• Low Power Consumption: Optimized for low power consumption, suitable for energy-efficient embedded systems.
• DIP-28 Package: Comes in a 28-pin DIP package, ideal for prototyping and easy integration with standard breadboards and through-hole PCB designs.
