Shutdown current of PCA9515B

Please tell me shutdown current of PCA9515B, when PCA9515B is Vcc=3.3V and EN off.

    Unfortunately, after digging into some files on this part and browsing datasheets with similar parts such as the TCA9517, it appears that the "shutdown current" of buffers is not recognized as a spec and therefore was not tested.

    Is power consumption very critical in your application?

    I2C buffers are not generally used in mobile applications, so it seems to me that the shutdown current was never a big concern when compared to the current through the pull-up resistors on an I2C bus.
