SN54LVCH245A-SP: SN54LVCH245A-SP Radiation Data

Hugh,
This device is not specifically "radiation tolerant". The term radiation tolerant in and of itself is not very useful anyways. Most of our older logic devices were released for class V at one time based on customer request without testing nor a minimum radiation performance requirement. Unfortunately, most of these logic devices do not have significant radiation performance.
We do have three logic devices that were intentionally hardened. The AC00, AC02 and AC14.
All of the available radiation data for our products is available here: www.ti.com/.../space.html

There may be some third party data on a device published by NASA, or IEEE.

Wade
