Notes:
*1. Supply current when output is high is typically 1.0mA 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 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.
