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