LSF0102: LSF0102 and TXS0102 major difference?

Hi Team,

Customer is asking is it possible to replace LSF0102 by TXS0102 or vice-versa? (in case H/W can be changed)

Customer doesn't understand why we want both device to be exist.

LSF device looks better in speed and TXS looks like easier to use that don't need external resistor to pull-up.

Anything else?

Thanks!!

Andrew
