Texas Instruments' LSF family are bidirectional voltage level translators that operate from 1.0 V to 4.5 V (Vref_A) and 1.8 V to 5.5 V (Vref_B). 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 100 MHz for open-drain systems utilizing a 15 pF capacitance and 165 Ω pull-up resistor.
