Electrical Characteristics
(T
Notes:
*1. Supply current when output is high is typically 1.0mA less at V
*2. Tested at V
*3. This will determine the maximum value of R
*4. Matching characteristics refer to the difference between performance characteristics of each timer section in the monostable
*5. As reset voltage lowers, timing is inhibited and then the output goes low.
