Notes

24.These parameters are extrapolated from the input timing parameters (tKHKH - 250 ps, where 250 ps is the internal jitter. An input jitter of 200 ps (tKC Var) is already included in the tKHKH). These parameters are only guaranteed by design and are not tested in production.

25.tCHZ, tCLZ are specified with a load capacitance of 5 pF as in (b) of AC Test Loads and Waveforms. Transition is measured ±100 mV from steady-state voltage.

26.At any voltage and temperature tCHZ is less than tCLZ and tCHZ less than tCO.
