Quality Control: Learn More
Intel QC8251A is an NMOS serial I/O controller designed for asynchronous and bit-oriented communication. This component operates within a 4.5V to 5.5V supply voltage range, with a nominal 5V requirement. It features one serial I/O channel with a maximum data transfer rate of 0.0078125 MBps and supports NRZ data encoding/decoding. The Intel QC8251A is compatible with MCS 48, MCS 80, MCS 85, IAPX 86, and IAPX 88 bus architectures. Additional capabilities include selectable modem control inputs that can function as I/O lines. This device is housed in a 28-terminal CDIP package and operates within a temperature range of 0°C to 70°C. Applications for this component can be found in industrial automation and legacy communication systems.
