Quality Control: Learn More
The Intel QD8274 is a multi-protocol serial communication controller featuring two channels. It supports asynchronous, BIT, synchronous (BYTE, HDLC, SDLC), X.25, and BISYNC communication standards with NRZ data encoding. This NMOS device operates with a maximum clock frequency of 16 MHz and a maximum data transfer rate of 0.107421875 Mbps. It offers four DMA channels and includes selectable modem control inputs that can function as general-purpose I/Os. The QD8274 is compatible with MCS 48, MCS 85, MCS 51, IAPX 86, IAPX 88, IAPX 186, and IAPX 188 bus architectures, with an 8-bit external data bus. Packaged in a 40-terminal CDIP with a ceramic, glass-sealed body, it operates within a 0°C to 70°C temperature range and requires a 4.75V to 5.25V supply. This component is commonly found in industrial automation and telecommunications equipment.
