Buffers, Drivers, Receivers, Transceivers FAQ

How does the Bus Hold feature function?

Bus Hold retains the data input's last state whenever the data input goes to high-impedance, preventing floating inputs and eliminating the need for external pull-up or pull-down resistors.

What is the purpose of the internal series resistors?

The output ports have equivalent 26-Ohm series resistors built-in, which eliminates the requirement for adding external resistors to the circuit design.
