DUTY CYCLE CONTROL
To maintain a duty cycle of ± 5% at 50MHz, limit the load capacitance and/or power supply variation as shown in Figures 3
and 4. For a ± 2.5% duty cycle limit, see Figures 5 and 6. Figures 7 and 8 show duty cycle variation with temperature. Figure 9
shows typical TPD versus load. Figure 10 shows reset recovery time. Figure 11 shows output states after power up.
Best duty cycle control is obtained with a single
mP load and minimum line length.
