Bus buffer for 3.3V backplanes
The SN74LVTH125PW: Each of the four elements handles one bit, with the output enable controlling the bus connection. The supply range of 2.7V to 3.6V lets it run directly from a 3.3V rail, and the 32 mA source / 64 mA sink drive is sized for moderate fan-out on a backplane or memory bus.
