Intel QC8259A is an NMOS interrupt controller designed for compatibility with 8086, 8088, MCS-80, and MCS-85 microprocessors. This component features 8 external interrupt inputs and an 8-bit external data bus. It is housed in a 28-lead ceramic dual in-line package (CDIP) with through-hole mounting. The operating temperature range is from 0°C to 70°C, with a nominal supply voltage of 5V and a maximum of 5.5V. Typical applications include embedded systems and industrial automation where efficient interrupt management is critical. The package dimensions are 35.56mm in length and 15.24mm in width, with a terminal pitch of 2.54mm.
