description  
This data sheet provides complete design documentation for the second-generation devices of the TMS320  
family. This facilitates the selection of the devices best suited for user applications by providing all specifications  
and special features for each TMS320 member. This data sheet is divided into four major sections: architecture,  
electrical specifications (NMOS and CMOS), timing diagrams, and mechanical data. In each of these sections,  
generic information is presented first, followed by specific device information. An index is provided for quick  
reference to specific information about a device.  
ADVANCE INFORMATION concerns new products in the  
Copyright 1991, Texas Instruments Incorporated  
sampling or preproduction phase of development.  
Characteristic data and other specifications are subject to  
change without notice.
