This allows bidirectional voltage translations between 1.0 V and 5.0 V without the need for a direction terminal in open-drain or push-pull applications. LSF family supports level translation applications with transmission speeds greater than 100Mbps for open-drain systems utilizing a 30 pF capacitance and 250Ω pull-up resistor. When the An or Bn port is LOW, the switch is in the ON-state and a low resistance connection exists between the An and Bn ports. The low Ron of the switch allows connections to be made with minimal propagation delay and signal distortion. Assuming the higher voltage is on the Bn port when the Bn port is HIGH, the voltage on the An port is limited to the voltage set by Vref_A. When the An port is HIGH, the Bn port is pulled to the drain pull-up supply voltage (Vpu#) by the pull-up resistors. This functionality allows a seamless translation between higher and lower voltages selected by the user without the need for directional control.
