Buffers, Drivers, Receivers, Transceivers FAQ

How is the 3-state control managed?

The device uses four separate Output Enable inputs (OEn), one for each nibble. These pins can be shorted together to enable full 16-bit simultaneous operation.

What is the purpose of the internal series resistors?

The 25Ω resistors are integrated into the output path to dampen signal ringing and eliminate the need for discrete external termination resistors.
