3: This will determine the maximum value of RA+RB for 15V operation, The maximum total is R=20MΩ, and

for 5V operation the maximum total is R=6.6MΩ.

4: As reset voltage lower, timing is inhibited and then the output goes low.

5: Matching parameters refer to the difference between performance parameters of each timer section in the

monostable mode.
