Advanced Micro Devices D8251 is a MOS technology serial I/O controller featuring a single communication channel. This component supports asynchronous, bit, synchronous byte, BISYNC, and external synchronous communication standards with NRZ data encoding/decoding. It operates with an 8-bit external data bus and is compatible with the 8080A bus architecture. The device has a maximum clock frequency of 2.38 MHz and operates within a temperature range of 0°C to 70°C. The D8251 is housed in a 28-pin CDIP package with a terminal pitch of 2.54mm, designed for through-hole mounting. Typical applications include industrial automation and data acquisition systems. The supply voltage range is 4.75V to 5.25V with a nominal 5.0V, and a maximum supply current of 80mA.
