Buffers, Drivers, Receivers, Transceivers FAQ

How is the 3-state output controlled?

The 3-state outputs are controlled by Output Enable (OE_n) inputs. When OE1 and OE2 are LOW, O0–O10 are in the 2-state mode. If either OE1 or OE2 is HIGH, the outputs enter a high impedance state.

What is the recommended configuration for unused control inputs?

Floating or unused control inputs must be held HIGH or LOW to ensure proper device operation and prevent undefined states.
