LM8300: Decode decoder ring required.....

Part Number: LM8300

I need to decode the markings on the LM8300IMT9B Touch Screen Controller.  The parts have two lines of marking with the second being the PN.  What I think are the date codes for the two parts are - 4AADHDUG3 and 67AVNXUG3.  They do not seem to follow TI convention.  I am most interested in the date code but would like to understand the entire string.

    Hi Ken,

    Welcome to our e2e forum! The LTC consists of 7 digits/letters - the first two are Year and Month (think HEX for the month). Your 4Axxxxx device would be 2004 October (edited, sorry 'bout that) and the 67xxxxx would be 2006 July. The additional letters represent assembly sites, etc.
