SN75971B2DGG Description

Short technical summary and product information.

The SN75971B2DGG from Texas Instruments is a 9-channel RS-485 transceiver that facilitates high-voltage differential SCSI communication from a single-ended controller. When paired with the SN75970B control transceiver, it enables the implementation of differential SCSI buses, including 16-bit Ultra-SCSI (Fast-20) configurations using minimal external components.

 

This transceiver meets or exceeds EIA Standard RS-485 and ISO-8482 standards. It features ESD protection on bus pins up to 12 kV, thermal shutdown protection, and positive/negative current limiting. The device also includes power-up/-down glitch protection and open-circuit failsafe receivers.

 

Packaged in a 56-pin TSSOP, the SN75971B2DGG is suitable for surface mounting. It operates within a temperature range of 0°C to 70°C and requires a supply voltage between 4.75V and 5.25V. The transceiver supports half-duplex communication.

 

This component is available in B2 (20 MT/s) and B1 (10 MT/s) versions, offering flexibility for different data rate requirements in SCSI implementations.
