Buffers, Drivers, Receivers, Transceivers FAQ

How are unused inputs handled in this device?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using pull-up or pull-down resistors to prevent undefined operational states.

What is the function of the x OE pins?

The x OE pins are active-low output enables. When low, the respective bank of buffers is enabled; when high, the outputs enter a high-impedance state.
