SN75LBC978 9 通道差动收发器
The SN75LBC978 is a nine-channel differential transceiver based on the 75LBC176 LinASICTM cell. Use of TI’'s LinBiCMOSTM
. On-chip enabling logic makes this device applicable for the data path (eight data bits plus parity) and the control path (nine bits) for the Small Computer Systems Interface (SCSI) standard. The WRAP function allows in-circuit testing and wired-OR channels for the BSY, RST, and SEL signals of the SCSI bus.
The SN75LBC978 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 of the SN75LBC978 is sufficient to transfer data over the data bus at 10 million transfers per second
