Notes: 1.Supply current when output is high is typically 1mA less at VCC 5V.
2. Tested at VCC=5V and VCC=15V.
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.
