SN74AHCT240: Clarify Truth Table in Datasheet

Part Number: SN74AHCT240

Hello,

We have a customer who is asking the following:

"Need confirmation truth table SN54/74AHCT240 on the data sheet:
data sheet revision 2003
Input 1         Input 2             Output
    L                   H                       L
    L                   L                        H
    H                  X                        Z

data sheet revision 2016
Input 1         Input 2             Output
    L                   H                       H
    L                   L                        L
    H                  X                        Z

Need those data to support our evaluation here".

I looked through the PCN's and old datasheets, am not finding anything to support a logic output change. It appears that the latest datasheet is the only place this logic table output exists.

Could someone please look into this?

Thank you,
Gabe Garza
