If SPI traffic through TXB0104-Q1 are starting before the devise are powered up, what will happen? Will it be harmful for the device? (VCCA and VCCB will be unpowered…)

The recommended operating conditions and absolute maximum ratings allow any voltage to applied to the I/Os in the power-off state.

Hey Bob,

This device has Ioff keeping the I/Os disabled when the device has 0 V on either supply. The abs max table provides the voltage levels that can safely be applied to the I/Os in the disabled state.
