1. A good quality 0.01uF in parrallel with a 0.1 uf capacitor should be located as close to pin 16 to ground as possible.
2. Figure 1 defines these parameters. Figure 2 illustrates the equivalent five-gate TTL load and operating conditions under which these parameters are
tested and specified. Loads greater than 15 pF will adversely effect rise/fall time and duty cycle.
3. Symmetry is defined as (ON TIME/PERIOD with Vs=-1.4 V for both 5V and 3.3V operation.
