1] Stability includes initial accuracy, temperature and aging.
2] A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
3] Figure 2 defines these parameters. Figure 1 illustrates the operating conditions under which these parameters are tested and specified.
4] Duty Cycle is measured defined as On Time/Period.
5] Measured using a Wavecrest SIA3300C, 90K samples
6] Output will be active if Enable/Disable is left open.
