SN75971B Overview
GND 14 GND 15 43 GND 42 GND The SN75971B SCSI differential converter-data is a 9-channel RS-485 transceiver. When used in conjunction with its panion control transceiver, the SN75970B, the resulting chip set provides the superior electrical performance of differential SCSI from a single-ended SCSI bus or controller. An 8-bit SCSI bus NC 26 31 BDB1 + requires only one data and one control transceiver.
