SN74HC4851-Q1: Does SN74HC4851-Q1 have internal clamp diodes?

My customer prefers internal clamp diodes at the inputs of an 8:1 mux. Can you please confirm if SN74HC4851-Q1 has internal clamp diodes at the inputs?

    Whitney,

    The SN74HC4851-Q1 has ESD protection diodes on the signal path.  You can see this information in the absolute maximum ratings by the +/-0.5 V limit.  This limit is due to the forward bias voltage of those diodes is about 0.5 V. 

    Thank you,

    Adam
