SN74HC244: what's Vih for VCC=3.3V?

Part Number: SN74HC244


in our datasheet we only gives Vih at VCC=2V, 4.5V, 6V.

But my customer is using Vcc=3.3V, so they would like to know Vih at this level.

And we also mentioned that the output can drive 6mA, do we have the output drive current vs output voltage plot? I believe the output voltage will drop as long as the output current increases.
