1
This is the difference between any two similar delay paths while operating at the same voltage and temperature.
2
Corresponding CMOS drivers set to A for noninverting and B for inverting.
3
The maximum delay that can be used is a little less than one-half the period of the clock. A longer delay disables the output.
4
Incremental delay; does not include propagation delay.
5
All delays between zero scale and full scale can be estimated by linear interpolation.
