A bus buffer can include a data buffer and a clock signal buffer. The data buffer for can include two symmetrical buffer circuits with an output signal that can follow the input voltage to provide bi-directional buffer action for a data path of the bus buffer. The clock buffer can operate in a forward or reverse direction, where the signal direction for the clock signal path in the bus buffer can be controlled with a direction input. The bus buffer can also include an enable circuit for enabling the data path and the clock signal path.
