8.3.1 Auto Bidirectional Voltage Translation

The LSF0102-Q1 device is an auto bidirectional voltage level translator that operates from 0.95 to 5.5 V on Vref_A and 1.8 to 5.5 V on Vref_B. This allows bidirectional voltage translation between 0.95 V and 5.5 V without the need for a direction pin in open-drain or push-pull applications. The LSF0102-Q1 device supports level translation applications with transmission speeds greater than 100 Mbps for open-drain systems using a 250-Ω pull-up resistor with a 30-pF capacitive load.
