The SN75LBC971A SCSI differential converter-data is an adaptation of the industry's first 9-channel RS-485 transceiver, the SN75LBC976. When used in conjunction with its companion control transceiver, the SN75LBC970A, the resulting chip set provides the superior electrical performance of differential SCSI from a single-ended SCSI bus or controller. A 16-bit SCSI bus can be implemented with just three devices (two data and one control) in the space efficient, 56-pin, shrink small-outline package (SSOP) and a few external components. An 8-bit SCSI bus requires only one data and one control transceiver.
