Favorite logic family
 

What's your favorite logic family?

Mine is dynamic domino, footless, n-only...

static cmos is always the good ol' standby tho..

The Holmes family. You know, Sherlock and his brother.

Solenoids are cool, too.

I used to play/work with TTL & Cmos.

Never heard of the others you listed.

haha. I was always a bigger fan of Columbo, the murder mystery in reverse.

Oh, that's nice. static CMOS is tried and true. Dynamic logic is basically you split it up into two stages, precharge and discharge, and its called dynamic because you 'precharge' the internal (low-impedance) node to 1 (VDD) and then it either remains at VDD or goes to ground depending on your logic. Dynamic is fast because you only need to have either a pull-up or pull-down network, not both like static CMOS. Of course, the constant act of precharging means a lot of energy, which is why dynamic is reserved for only the most speed-critical tasks.

I understand about half of that :-)

It would be more efficient to charge only when needed. (sorta the reverse of what you described). Duh.

I suppose the precharge takes place before the logic is tested (precharge) and to just discharge as needed is fast. Duh again.

I wonder how much current is required for this family compared to TTL or Cmos.

This page seems to describe and compare the families.

I can follow some of it :-)
