Overview
The SN75160B, specifically the SN75160BDWR model, is an 8-channel general-purpose interface bus (GPIB) transceiver produced by Texas Instruments. This monolithic, high-speed, low-power Schottky device is designed for two-way data communications over single-ended transmission lines. It meets the requirements of IEEE Standard 488-1978, making it suitable for a wide range of applications involving GPIB interfaces.
The transceiver features driver outputs that can operate in either passive-pullup or 3-state mode, depending on the talk enable (TE) and pullup enable (PE) signals. It is characterized for operation from 0°C to 70°C and is part of a family of devices that, when combined with the SN75161B or SN75162B, provide a complete 16-wire interface for the IEEE-488 bus.
