Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

The device contains two separate output-enable (OE) inputs. When OE is low, data passes from inputs to outputs; when high, outputs enter a high-impedance state.

What is the input voltage compatibility?

The inputs are TTL-voltage compatible, allowing direct interfacing with standard TTL logic sources.
