The Advanced Micro Devices D8259A, part of the D8259 series, is an NMOS interrupt controller designed for use with microprocessors such as the 8080A, 8085AH, 8086, and 8088. This component features eight external interrupt request inputs, enabling efficient management of peripheral device interrupts. It operates with an 8-bit external data bus and is housed in a 28-lead Ceramic Dual In-line Package (CDIP28), specifically R-GDIP-T28, with through-hole mounting and a terminal pitch of 2.54mm. The operating temperature range is from 0°C to 70°C, with a nominal supply voltage of 5.0V, ranging from 4.5V to 5.5V, and a maximum supply current of 85mA. This device is commonly found in legacy computing systems, industrial automation, and embedded control applications where robust interrupt handling is critical.
