Introduction
The LSF series includes bidirectional voltage level translators operating across voltage ranges of 0.8V to 4.5V (Vref_A) and 1.8V to 5.5V (Vref_B). This range supports bidirectional voltage translation between 0.8V and 5.0V without requiring direction terminals in open-drain or push-pull applications. For open-drain systems using 15pF capacitors and 165Ω pull-up resistors, the LSF series supports level translation applications at transfer speeds greater than 100MHz. When an An or Bn port is driven low, the switch is turned on, establishing a low-resistance connection between the An and Bn ports. The low R_on of the switch enables connections with ultra-small propagation delay and signal distortion. The voltage on the A or B side is clamped to Vref_A and can be pulled up to any voltage level between Vref_A and 5V. This feature enables seamless translation between user-selected higher and lower voltages without direction control. The supply voltage (V_pu#) for each channel can be individually configured with pull-up resistors. For example, CH1 can be used in up-translation mode (1.2V↔3.3V) while CH2 can be used in down-translation mode (2.5V↔1.8V). When EN is high, the translator switches are closed and the An I/Os are connected to their respective Bn I/Os, enabling bidirectional data flow between ports. When EN is low, the translator switches are open and the ports are in a high-impedance state. The EN input circuit is designed to be powered by Vref_A. EN must be held low to ensure a high-impedance state during power-up or power-down.
