NOTES:
1. Supply current when output high typically 1mA less.
2. Tested at V

=5V and V
CC
=15V.
3. This will determine the max value of R

, for 15V operation, the max total R=10MΩ, and for 5V operation, the max. total R=3.4MΩ.
4. Specified with trigger input high.
5. Time measured from a positive going input pulse from 0 to 0.8×V
CC
into the threshold to the drop from high to low of the output. Trigger is
tied to threshold.
