Electrical Characteristics
Values are at T
A
= 25°C, V
CC
= 5 ~ 15 V unless otherwise specified.
Notes:
1. When the output is high, the supply current is typically 1 mA less than at V
CC
= 5 V.
2. Tested at V
CC
= 5.0 V and V
CC
= 15 V.
3. These parameters, although guaranteed, are not 100% tested in production.
4. This determines the maximum value of R
A
+ R
B
for 15 V operation, the maximum total R = 20 MΩ, and for 5 V
operation, the maximum total R = 6.7 MΩ.
