Texas Instruments Interface - Drivers, Receivers, Transceivers SN75971B2DLR

The SN75971B2DLR is a 9-channel RS-485 transceiver designed for high-voltage differential SCSI applications. It operates in conjunction with the SN75970B control transceiver to convert single-ended SCSI signals to differential SCSI, enabling efficient communication over a 16-bit Ultra-SCSI or Fast-20 SCSI bus with minimal external components. The device is packaged in a 56-pin shrink small-outline package (SSOP) or thin small-outline package (TSSOP) and features low disabled-supply current of 32 mA typical, thermal shutdown protection, and ESD protection on bus pins up to 12 kV. The transceiver supports both single-ended and differential data transfer modes, with independent direction control for each data bit. It includes open-circuit failsafe receivers and power-up/down glitch protection. The operating temperature range is specified from 0°C to 70°C, making it suitable for various applications. This product meets or exceeds EIA-485 and ISO-8482 standards, ensuring reliable performance in differential signaling environments.
