TXB0304: Doubt in Pin Description

Karthik K

Part Number: TXB0304

Tool/software:

In the Figure I have marked two red boxes, one for pin A4 and one for B4. Here in both the pins the description is shown differently. For A4 it is mentioned as Input/Output 4 and for B4 it is mentioned as Input/Output 1. Please provide a clear statement for this.

    This is an error in the "Description" column.

    The pins are numbered counterclockwise around the chip, which means that the pin numbers (but not pin names) of the output pins are in reverse, relative to the input pins.

    The table shows the pin names (A1, B1, etc.) in order. Therefore, the pin numbers of the output pins are in reverse order. The pin names and numbers are correct, the description is not.

    (An older revision of the datasheet showed the pin numbers in order, so the output pin names were in reverse. That revision showed the channel numbers in the description column in order, which also was wrong. Apparently, there was an attempt to fix the order of the rows, but it kept the wrong description with each row.)
