Chip Alternative

Hello,

I am building the frequency counter described here: Frequency Counter.
It uses the MC10116N triple ECL differential line receiver chip, but it is hard to find (Not in stock at Digikey or Newark).
Is there a replacement part that I could obtain more easily. I was hoping to order it though Newark.

Thanks in advance,

Cameron

Thank you for your quick reply.
Looking at the datasheet, I see that the MC10H116PG is just an improved version of the MC10116N.
