TCA9539-Q1: The voltage tolerance of P00–P07 and P10–P17

Part Number: TCA9539-Q1

Hi,TI team:

     From the datasheet, when  P00–P07 and P10–P17 use as input,the voltage tolerance of P00–P07 and P10–P17  are 5.5V,am I right?

    Can I use like this: the VCC is 1.8V, the P00–P07 and P10–P17 use as input, the VOH of  P00–P07 and P10–P17  are 3.3V?
