And posybly higher frequency switching

CMOS has safety problems with static, can deliver less ouput current(compare cmos 555 timer with the non-cmos),you cannot leave any input open when experimenting. TTL circuits facing the outside world are more robuust,having buildin pullup currents on inputs works very nice when interfacing switches, any input when open is in the "1" state, I leave the rest of the advanteges to other people. Now start flaming!!....
