Hello April,
For the TXB0102 (and all devices in the TXB family), the unused pins can be:

(1) Both tied to ground
(2) Both left floating
(3) One tied to ground, the other left floating
(4) Each connected directly to its appropriate supply (A1 to VCCA, B1 to VCCB)
(5) One tied to its appropriate supply V_CC(A/B), the other left floating
