1. A good quality 0.01uF in parrallel with 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.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability.

Although ESD protection circuitry has been designed into the TRU050, proper precautions should be taken when handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model.
