SN74LVC2G00: different Pin designation for DSBGA

Part Number: SN74LVC2G00

Hi there

Datasheet, page 3 are the pin configurations.
For YZP package (DSBGA) the pins are named as 1, 2, 3, .....

Page 17: footprint pins are defined with A1, B1, ..... .

What is the correct pin naming for SN74LVC2G00YZPR?

In my view A1, B1, ..... is correct for DSBGA packages.

    With the (V)SSOP package, there are two ways to identify a pin: its name, or its number (from 1 to 8).

    With the DSBGA package, there are three ways to identify a ball: its name, its number (from 1 to 8), or its two-dimensional position in the grid.
    All three ways are correct.
