Texas Instruments LSF0204x/LSF0204x-Q1 Level Translators
Texas Instruments LSF0204x/LSF0204x-Q1 Bidirectional Multi-Voltage Level Translators are bidirectional voltage level translators that operate from 1.0V to 4.5V (Vref_A) and 1.8V to 5.5V (Vref_B). This allows bidirectional voltage translations between 1.0V and 5.0V without the need for a direction terminal in open-drain or push-pull applications. LSF0204x supports level translation applications with transmission speeds greater than 100MHz for open-drain systems utilizing a 15pF capacitance and 165Ω pull-up resistor. The LSF0204x-Q1 devices are AEC-Q100 qualified for automotive applications.
