SN75C091AFN

SCSI Bus Controller, CMOS, PQCC68

Manufacturer: Texas Instruments

Categories: Bus Controllers

Quality Control: Learn More

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.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
