TXB0304: Input/output numbering in datasheet seems incorrect

Simon Ask
Prodigy 50 points
Part Number: TXB0304

Hi,

Looking at the datasheet for the TXB0304 the definitions of the ports are as following (page 3):

A1: Input/output 1
A2: Input/output 2
A3: Input/output 3
A4: Input/output 4

B1: Input/output 4
B2: Input/output 3
B3: Input/output 2
B4: Input/output 1

Is this really correct? Usually A1 goes to B1 etc. The signal directions in section 11.2 would then also make more sense.

Best regards,
Simon

    Hey Simon,

    This looks to be a typo, thanks for highlighting this I will add it to our errata list to get fixed in future updates. The number in the description is supposed to correspond to the number in the pin name. For example, A1 and B1 are the A and B ports of channel 1.
