●The SN75LBC976 is a nine-channel differential transceiver based on the 75LBC176 LinASICTM cell. Use of TI"s LinBiCMOSTM[dagger] 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.
●The SN75LBC976 is packaged in a shrink small-outline package (DL) with improved thermal characteristics using heat-sink terminals. This package is ideal for low-profile, space-restricted applications such as hard disk drives.
●The switching speed and testing capabilities of the SN75LBC976 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 SN75LBC976 is characterized for operation from 0°C to 70°C.
