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 1 and 2.
For a ±2.5% duty cycle limit, see Figures 3 and 4. Figures 5 and 6 show duty cycle variation with temperature. Figure 7 shows typical
TPD versus load. Figure 8 shows reset recovery time. Figure 9 shows output states after power up.
Best duty cycle control is obtained with a single µP load and minimum line length.
