The Intel QP8251A is a single-channel serial I/O controller from the QP8251 series, operating with NMOS technology in a 28-pin PDIP package. It supports asynchronous, BIT, synchronous byte, BISYNC, and extended synchronous communication standards. The device features modem control inputs selectable as I/O and is compatible with MCS 48, MCS 80, MCS 85, IAPX 86, and IAPX 88 bus architectures. The maximum data transfer rate is 0.0078125 MBps. Operating within a temperature range of 0°C to 70°C, it requires a supply voltage between 4.5V and 5.5V, with a nominal value of 5.0V. This component is suitable for applications in telecommunications and industrial automation.
