The SN75970B SCSI differential convertercontrol, when used in conjunction with one or more of its companion data transceiver(s), provides the superior electrical performance of differential SCSI from a single-ended SCSI bus controller. A 16-bit, Fast-SCSI bus can be implemented with just three devices (two for data and one for control) in the space-efficient, 56-pin, shrink small-outline package (SSOP) as well as the even smaller TSSOP and a few external components.
