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 W, and

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

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.
