Intel TN8259A is an 8-bit programmable interrupt controller designed for compatibility with 8086, 8088, MCS-80, and MCS-85 microprocessors. This NMOS device features 8 external interrupt request lines, supporting prioritized interrupt handling within embedded systems. With an 8-bit external data bus, it facilitates seamless integration into legacy and modern designs. The TN8259A is housed in a 28-lead J-bend PQCC (Plastic Quad Flat Chip Carrier) package, suitable for surface-mount applications. Operating within a temperature range of -40°C to +85°C and utilizing a nominal supply voltage of 5.0V, this component is utilized in industrial automation and embedded computing applications requiring robust interrupt management.
