NOTES:
1. Supply current when output high typically 1 mA less.
2. Tested at VCC = 5 V and VCC = 15 V.
3. This will determine the max value of RA+RB, for 15 V operation, the max total R = 10 M, and for 5 V operation, the max. total R = 3.4 M.
4. Specified with trigger input HIGH.
5. Time measured from a positive-going input pulse from 0 to 0.8
×VCC into the threshold to the drop from HIGH to LOW of the output. Trigger is
tied to threshold.
