Logic Outputs:-
Logic outputs are square waves designed to drive particular series or type of logic. Three comon types are TTL, CMOS and ECL.
The output alternates between logic 0 and logic 1.

Some of the features are:-
Rise and fall times:- The times taken to rise and fall between specified levels, usually the logic 0 and logic 1 levels, measured in nanoseconds.

Symmetry:- The fraction of the time that the output spends above a certain level, usually half way between the logic 0 and logic 1 levels. Measured in percent.

VOH and VOL:-Output high voltage and output low voltage. The maximum and minimum voltage that the output gets to. The minimum VOH and the maximum VOL are usually the logic 1 and logic 0 levels.

Output load:- The maximum load that the oscillator will drive while garuanteed to meet the specified waveform criteria.
