74HC series RF output impedance

Hi,

Has anyone a pointer to the RF output impedance of the 74HC
series gates (at about 10MHz)? I have a few inverters/buffers
left over in a package and thought of using them stacked to drive
an output port via a simple matching network. I've seen this done
before and have simulated it myself but would like it spelled
out.

Cheers - Joe, G3LLV
