Notes:
*1. Supply current when output is high is typically 1.0mA less at V
= 5V
CC
*2. Tested at V
CC
= 5V and V
= 15V
CC
*3. This will determine the maximum value of R + R for 15V operation.
A
B
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.
