Note 1: Supply current when output is high is typically 1mA less at Vcc 5V.
Note 2: Tested at Vcc=5V and Vcc=15V.
Note 3: This will determine the maximum value of RA+RB for 15V operation, The maximum total is R=20M
Ω, and
for 5V operation the maximum total is R=6.6M
Ω.
Note 4: As reset voltage lower, timing is inhibited and then the output goes low.
Note 5: Matching parameters refer to the difference between performance parameters of each timer section in the
monostable mode.
