Clamp Diodes on analog pins of the CD54HC4051

I have a question regarding the TI CD54HC4051 device, and the datasheet is attached.  Are there clamping diodes on the analog I/O signals?  If so, what is the maximum current thru those diodes?  There doesn’t appear to be any clamping diodes according the datasheet, but I want to be absolutely sure of it.
