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.
