1. Tested at V
CC
= +5 V and V
CC
= +15 V.
2. This will determine the maximum value of R
A
+ R
B
for 15 V operation. The maximum total (R
A
+ R
B
) is 20 MΩ for +15 V
operation and 3.5 MΩ for +5 V operation.
3. Specified with trigger input high.
4. No protection against excessive pin 7 current is necessary, providing the package dissipation rating is not exceeded.
5. Time measured from a positive pulse (from 0 V to 0.8 x V
CC
) on the threshold pin to the transition from high to low on the
output pin. Trigger is tied to threshold.
