SN74ABT541B: Input Clamp Diode

Tool/software:

Team, I'd like to confirm if this device has only low side clamp diode as VI<0, IIK=-18mA and High side has no clamp diode on the input pin? thanks.

One more question, when VCC = 0V, and Input voltage is 3V or 5V. With this condition, does device work normally? Or is it risky?

When VCC = 0 V, larger input voltages are allowed by the absolute maximum ratings. No current will flow, and the device will not power up.
