SN55976A1WD Description

Short technical summary and product information.

The Texas Instruments SN55976A1WD is a 9-channel differential transceiver, suitable for Small Computer Systems Interface (SCSI) and Intelligent Peripheral Interface (IPI) applications. This device is an improved replacement for the SN75LBC976, offering enhanced switching performance, a smaller package, and higher ESD protection.

 

Designed to operate at speeds up to 20 Million Data Transfers per Second (Fast-20 SCSI), the SN55976A1WD features nine differential channels for data and control paths. It provides ESD protection on bus terminals exceeding 12 kV and has a low disabled supply current of 8 mA typical. The operating temperature range is -55°C to 125°C, making it suitable for military applications.

 

This transceiver is packaged in a 56-pin Ceramic Flat Pack (WD). It includes features such as thermal shutdown protection, positive- and negative-current limiting, and power-up/down glitch protection. The SN55976A1WD is available in versions with specific skew limits to comply with SCSI standards.
