TXS0102: VCCA and VCCB power on supply sequence

Tool/software:

I wish to use the TXS0102 to interface external signals on the side B, with a xilinx FPGA connected to the side A.
Due to the FPGA Power-On/Off Power Supply Sequencing, I want provide immediately Vccb, and, only later, i will provide Vcca (at the end of FPGA power-on sequence)
I need to know if the TXS0102 can work in this way, or, if problems can arise in the short period in which power supply is provided only on VCCb pin.

thank you in advance for your help.
