TXB0104: Leakage question

AJ Cheng

Part Number: TXB0104

Hello

Our application is Vcca and Vccb are no power and OE is low. Will the Ax data leak to the Bx side?

Other application is Vcca(1.8V) and Vccb(no power) and OE is low. Will the Ax data leak to the Bx side?

Thanks for help~

    Hello,

    Since the TXB0104 has Ioff and Voltage isolation features, whenever either of the supply's is at GND then all the IO's go into high impedance mode.
    This means that data will not leak from one side to the other.
    There is an Ioff spec in the datasheet that says max of +/- 1 uA might leak through the IO's when the supplies are at GND.

    Thanks!
