Hello Sir:

I would like to use TXS0102 in push-pull application, but I am confused about that

in TXB0102, if VCCA=0(not ready), but A1 comes early, there is no leakage(I have verified) but I am worried about in

my case, is there current flow from A1 to VCCA since pull-high 10K resistor ?

TXB0102 is designed to be interfaced with push-push drivers and TXS0102 is designed to be connected with open-drain driver.

If connect 10KΩ between VCCA and TXB0102 A1 port, there is current when A1 is low. If pull-up resistor is necessary, the value should be greater than 50KΩ. Please refer application note for TXB-type translators.
