Electrical Characteristics
(T
A
= 25°C, V
CC
= 5 ~ 15V, unless otherwise specified)
Notes:
1. Supply current when output is high is typically 1.0mA less at V
CC
= 5V
2. Tested at V
CC
= 5V and V
CC
= 15V
3. This will determine the maximum value of R
A
+ R
B
for 15V operation.
The maximum total R = 20MΩ, and for 5V operation the maximum total R = 6.6MΩ.
4. Matching characteristics refer to the difference between performance characteristics of each timer section in the monostable
mode.
5. As reset voltage lowers, timing is inhibited and then the output goes low.
