Loads

1. Other frequencies may be available, please contact factory with your special requirements.

2. A 0.1 mF low frequency tantalum bypass capacitor in parallel with a 0.01 mF high frequency ceramic capacitor is recommended. Both should be located as close to the FTU-Type bias pin as is practical

3. Figure 1 defines these parameters. Figure 2 illustrates the equivalent TTL load and operating conditions under which these parameters are specified and tested.
