The Advanced Micro Devices MD8251AB is a single-channel serial I/O controller within the MD8251 series. Operating with NMOS technology, this component is housed in a 40-pin CDIP package. It supports asynchronous, bit-synchronized, byte-synchronized, BISYNC, and external synchronous communication standards, utilizing NRZ data encoding. The maximum data transfer rate is 0.0078125 MBps. This controller is compatible with 8080, 8085, 8086, and 8088 bus architectures and features an 8-bit external data bus. Designed for robust operation, it functions across an extended temperature range of -55°C to +125°C and requires a supply voltage of 4.5V to 5.5V. Screening is performed to MIL-STD-883 Class B (Modified). Applications for this component are found in industrial automation and telecommunications systems.
