Notes:
6. This parameter influences the maximum value of the timing resistors R and R in the circuit of Figure 12. For example, when V
= 5 V, the

maximum value is R = R + R ≉ 3.4MΩ, and for V = 15 V, the maximum value is 10MΩ.

7. No protection against excessive pin 7 current is necessary providing package dissipation rating is not exceeded
8. Timing interval error is defined as the difference between the measured value and the average value of a random sample from each process run.
9. Values specified are for a device in a monostable circuit similar to Figure 9, with the following component values: R = 2kΩ to 100kΩ, C = 0.1uF.

10. Values specified are for a device in an astable circuit similar to Figure 12, with the following component values: R = 1kΩ to 100kΩ, C = 0.1uF.
