[time-nuts] Distribution amplifier for 10MHz and 1 pps

[Taka Kamiya]

I'm very curious, too.  Especially when I *just* built one using 74HC04N.

Could you please say more?  Do you mean logic family selection, or chip 
selection within a family?

Most modern digital chips are CMOS with an input threshold of VCC/2.  I'd 
expect power supply noise to be important and families with faster switching 
times probably make more noise.
