Hello buddies!

I am wondering how to know which is the maximum frequency which is able 
to manage this buffer/driver: 74LVC126

I need it for drive a 150MHz. and I can't see any reference in the 
datasheet...

Thanks!

What datasheet?
In that one from NXP there's a complete page with timing figures:

What kind of signal? A simple 50:50 clock signal? What rise and fall 
times does your design allow to that signal?

it is a simple 150MHz clock signal wit 50% of duty cycle. It is to drive 
a sensor so in the beginning there is not any restriction but have a 
look that if the clock=150 MHz, it meand that the period is 6.6ns. So I 
dont know how to manage this in order to have a good clokc at the 
ouutput....
