Note: This parameter influences the maximum value of the timing resistors R_A and R_B in the circuit of Figure 2. For
example, when V_CC=5V, the maximum value is R=R_A+R_B≠3.4MΩ, and for V_CC=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: R_A=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: R_A=1kΩ~100kΩ, C=0.1µF.
