TMS320DM8168: Long term availability

Hi, Rama,

Product longevity is important to TI and its customers. We recognize that our products are sold to a wide variety of customers and used in a wide range of applications with expected production lifetimes often in excess of several years, including industrial, medical, and automotive applications. 

We are dedicated to meet customer needs and, as such, we employ strategies such as inventory management and multiple sourcing tactics to address continuity. 

Here is an external link to TI's GQC (General Quality Guidelines)

You can look at the documents as well as FAQ on product withdrawl and discontinuance. I hope this helps.
