The Texas Instruments SN75C091AFN is a CMOS SCSI bus controller designed for high-performance data transfer. Operating with a supply voltage range of 4.75V to 5.25V, this component supports a maximum clock frequency of 20 MHz and a peak data transfer rate of 5 MB/s. It features an 8-bit external data bus and a 5-bit address bus, facilitating robust communication within SCSI-based systems. The SN75C091 series controller is housed in a 68-terminal square plastic chip carrier (PQCC68) package with J-bend terminals and a 1.27mm terminal pitch, suitable for surface-mount applications. This component finds utility in industrial automation, storage systems, and high-end computing platforms requiring reliable peripheral connectivity adhering to the X3.131 standard. The operating temperature range is from 0°C to 70°C, with a maximum supply current of 30mA.
