Notes: 1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating

conditions.

2. Timing interval error is defined as the difference between the measured value and the average value of a

random sample from each process run.

3. Values specified are for a device in a monostable circuit similar to Figure 1, with the following component

4. Values specified are for a device in an astable circuit similar to Figure 2, with the following component
