9-CHANNEL DIFFERENTIAL TRANSCEIVER

SN55LBC976 9-CHANNEL DIFFERENTIAL TRANSCEIVER SGLS091A – JUNE 1995 – REVISED JANUARY 1997 D Nine Differential Channels for the Data and Control Paths of the Differential Small Computer Systems Interface (SCSI) and Intelligent Peripheral Interface (IPI-2) D Meets or Exceeds the Requirements of ANSI Standard RS-485 and ISO 8482:1987(E) D Packaged in 380-mil Fine Pitch Ceramic Flat (WD) Package Using 25-mil Center-to-Center Spacing D Designed to Operate at 10 Million Transfers Per Second D Low Disabled Supply Current 1.4 mA Typical D Thermal Shutdown Protection D Power-Up/Power-Down Glitch Protection D Positive and Negative Output Current Limiting D Open-Circuit Fail-Safe Receiver Design description The SN55LBC976 is a 9-channel differential transceiver based on the SN55LBC176 LinASIC™ cell. Use of TI’s LinBiCMOS™† process technology allows the power reduction necessary to integrate nine differential transceivers. On-chip enabling logic makes this device applicable for the 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.
