The SN55LBC976 is a 9-channel differential  
transceiver based on the SN55LBC176  
†
LinASIC cell. Use of TI’sLinBiCMOS process  
technology allows the power reduction necessary  
to integrate nine differential transceivers. On-chip  
enablinglogicmakesthisdeviceapplicableforthe  
data path (eight data bits plus parity) and the  
control path (nine bits) for both the Small  
Computer Systems Interface (SCSI) and the  
Intelligent Peripheral Interface (IPI-2) standard  
data interfaces.  
9DE/RE  
The switching speed and testing capabilities of the SN55LBC976 are sufficient to transfer data over the data  
bus at 10 million transfers per second. Each of the nine channels conforms to the requirements of the ANSI  
RS-485 and ISO 8482:1987(E) standards referenced by ANSI X3.129-1986 (IPI), ANSI X3.131-1993 (SCSI-2),  
and the proposed SCSI-3 standards.  
The SN55LBC976 is characterized for operation from –55°C to 125°C.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
