LSF0102: Questions of LSF0102

Part Number: LSF0102

Dear Team,

I have a question, the level conversion chip LSF0102DCTR converts 3.3V to 1.8V. Does it have the turn-on voltage VIH value?

I compared the waveforms on both sides, as shown below. It can be seen from the waveform that there is no turn-on voltage. Both sides are driven by pull-up resistors.

Rising: 1.8V rises following 3.3V and stabilizes at 1.8V; falling: After 3.3V drops to 1.8V, the 1.8V at terminal A begins to drop (terminal A is 1.8V, terminal B is 3.3V)

Please confirm, thank you!

Many Thanks,

Jimmy
