1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
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.
3. Symmetry is defined as (ON TIME/PERIOD with Vs=-1.4 V for TTL and Vs=2.5 V for CMOS, 5 volt operation, and Vs=1.65V for
3.3 Volt operation.
4. Load Capacitor will depend on frequency.
