Texas Instruments SN75971B SCSI Differential Converter-Data Datasheet

About this manual

The SN75971B SCSI Differential Converter‑Data provides high‑voltage differential SCSI interfaces for use with a companion control transceiver (SN75970B). It meets EIA‑485 and ISO‑8482 standards and includes ESD protection, thermal shutdown, and current‑limiting features. The device is offered in shrink‑small‑outline (SSOP) and thin‑shrink (TSSOP) packages.

Typical applications include converting single‑ended SCSI bus signals to a differential bus for improved noise immunity and longer cable runs. The datasheet details electrical characteristics, absolute maximum ratings, recommended operating conditions, and timing specifications.
