NOTE 2: This parameter influences the maximum value of the timing resistors R and R in the circuit of Figure 12. For example, when

= 5 V, the maximum value is R = R + R ≈ 3.4 MΩ, and for V

= 15 V, the maximum value is 10 MΩ

†

Timing interval error is defined as the difference between the measured value and the average value of a random sample from each process

run.

‡

Values specified are for a device in a monostable circuit similar to Figure 9, with component values as follow: R = 2 kΩ to 100 kΩ, C = 0.1 µF.

Values specified are for a device in an astable circuit similar to Figure 12, with component values as follow: R = 1 kΩ to 100 kΩ, C = 0.1 µF.
