SN74AVC32T245: can vccb have multiple values for the 4 different channels?

Hello -

Is it possible to have all 4 VCCAs at 1.2V and then have half of the VCCBs at 3.3V and the other half at 1.8V?  Just checking.  Pinout looks like there's a VCCA+B for each 8 channels.  Wondering if they're independent.

Thanks for the help
