The Advanced Micro Devices MD8259A is an 8-bit Programmable Interrupt Controller (PIC) within the MD8259 series. This NMOS technology device, manufactured by Advanced Micro Devices, offers 8 external interrupt inputs and features an 8-bit external data bus. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5.0V. The MD8259A is housed in a 28-terminal ceramic, metal-sealed cofired CDIP package (R-CDIP-T28) with through-hole termination and a terminal pitch of 2.54mm. Its operating temperature range spans from -55°C to +125°C, and it adheres to MIL-STD-883 Class C screening levels. This component is suitable for applications in industrial control, data acquisition systems, and legacy computing architectures requiring robust interrupt management.
