Other Parts Discussed in Thread: SN74CBTLV3257

Hi,

I am currently referring to the SN74CBTLV3257 datasheet version "SCDS040K" and I noticed there is a confusion in the datasheet regarding select signal.

1. As per Table -1 when S = 0, A port = B1 port.

2. Whereas in section 9.2.2 it is mentioned that when S = 0, A port = xB2 port.

As per Function block diagram in section 8-2, it seems that Table-1 is correct. Please confirm if this is a mistake in sec 9.2.2.

Regards,

Shareef

Hi Khader!

I cannot confirm this, but I share your opinion! I think the text is wrong. Maybe you want to submit document feedback at the bottom of the page in the datasheet.

Hi Dennis,

Thanks!
I can submit a request for document feedback. However I am using this part in the design and need a firm answer on which is correct.

Understandable!

Don't you have one to test?
