I2C Voltage 5V or 3,3V?

CrossRoads:
Why do say DS1307 is 5V only? Datasheet indicates it will work much lower:

Logic 1 Input, VIH: 2.2 to VCC + 0.3V
Logic 0 Input, VIL: -0.3 to +0.8V

Looks like a 3.3V capable part to me.

I was just looking at the datasheet at it's Vcc rating. But your right in that even though needing +5vdc Vcc power, it will still work on a 3.3volt I2C bus.
