Note: This parameter influences the maximum value of the timing resistors RA and RB in the circuit of Figure 2. For

example, when VCC=5V, the maximum value is R=RA+RB≠3.4MΩ, and for VCC=15V, the maximum value is

10MΩ.

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

values: RA=2kΩ~100kΩ, C=0.1µF.

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

values: RA=1kΩ~100kΩ, C=0.1µF.
