SN74AUC2G86: Inconsistency with pin numbering

Justin Fleming

Part Number: SN74AUC2G86

in document SCES479B, for the above part number the YZP package shows numbered pins on page 1, while on page 16 with the package information the pins are numbered using alph-numeric labeling.

Pin numbers, ball coordinates, and pin names are three different ways to identify pins.

1 = A1 = 1A
2 = B1 = 1B
3 = C1 = 2Y
4 = D1 = GND
5 = D2 = 2A
6 = C2 = 2B
7 = B2 = 1Y
8 = A2 = VCC

I understand that, however adding a 1-8 and an alpha numeric, aside from pin names seems to be unintentional, and could create confusion.

Hi Justin,

We don't control the numbering on the package information page. That's auto-populated with every datasheet. On the first page I think the numbering scheme actually works quite well with keeping things clear as to how the pins are ordered and oriented on the device between packages.

Best,

Malcolm
