Notes:
1. When the output is high, the supply current is typically 1mA less than at V
CC
= 5V.
2. Tested at V
CC
= 5.0V and V
CC
= 15V.
3. This will determine the maximum value of R
A
+ R
B
for 15V operation, the max. total R = 20MΩ, and for 5V operation, the max.
total R = 6.7MΩ.
4. These parameters, although guaranteed, are not 100% tested in production.
