TS5A3357: 3.3V logic compatibility at 5V rail

Part Number: TS5A3357
Other Parts Discussed in Thread: TS5A3359

Hi, We want to use this switch running at 5V power rail but controlled from MCU at 3.3V. Datasheet states that VIH is 0.7xV which for 5V gives 3.5V. Is this correct and does it mean it cannon be controlled from 3.3V logic?

Also if above is true does it mean that we should use pin compatible part TS5A3359 which VIH is from 2.4V?

Thanks and Regards,

Stefan
