cell. Use of TI’s LinBiCMOSprocess technolo-  
gy allows the power reduction necessary to  
integrate nine differential balanced 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 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.

Pins 13 through 17 and 40 through 44 are  
connected together to the package lead  
frame and signal ground.  
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. Each of the nine identical channels conforms to the requirements of the ANSI RS-485 and  
ISO 8482:1987(E) standards referenced by ANSI X3.131-1993 (SCSI-2) and the proposed SCSI-3 standards.  
The SN75LBC978 is characterized for operation from 0°C to 70°C.
