Notes:
6. This parameter influences the maximum value of the timing resistors R
A
and R
B
in the circuit of Figure 12. For example, when V
CC
= 5 V, the
maximum value is R = R
A
+ R
B
≉ 3.4MΩ, and for V
CC
= 15 V, the maximum value is 10M
Ω.
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
A
= 2k
Ω 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
A
= 1k
Ω to 100kΩ, C = 0.1uF.
