1. A 0.01uF and 0.1uF parallel capacitor should be located as close to pin 14 as possible (and grounded).
2. Figure 2 defines these parameters. Figure 3 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 as well as symmetry.
3. Symmetry is defined as (ON TIME/PERIOD with Vs=1.4 V for both 5.0 V and 3.3 V operation.
