Hi team,

When making 3.3V to 1.8V or 1.8V to 3.3V translation, what's the input VIH and VIL threshold? Thanks!

There are no thresholds. For voltages below Vref_A, the LSF works as an analog switch. For voltages at Vref_A or higher, the switch is open, and the voltage is determined by the pull-up resistor.

See [FAQ] How do the LSF translators work?
