NOTES:
1. Supply current when output is high is typically 1.0 mA less.
2. Tested at VCC = 5 V and VCC = 15 V.
3. This will determine maximum value of RA+RB. For 15 V operation, the max total R = 10 M, and for 5 V operation, the maximum total
R = 3.4 M
.
4. Matching characteristics refer to the difference between performance characteristics for each timer section in the monostable mode.
5. Specified with trigger input high. In order to guarantee reset the voltage at reset pin must be less than or equal to 0.4 V. To disable reset
function, the voltage at reset pin has to be greater than 1 V.
6. Time measured from a positive-going input pulse from 0 to 0.4 VCC into the threshold to the drop from high to low of the output. Trigger is
tied to threshold.
