Electrical Characteristics

(TA = 25

°C, VCC = 5 ~ 15V, unless otherwise specified)

Notes:

1. Supply current when output is high is typically 1mA less at VCC = 5V

2. Tested at VCC = 5.0V and VCC = 15V

3. This will determine maximum value of RA + RB for 15V operation, the max. total R = 20M

Ω, and for 5V operation the max. total

R = 6.7M

Ω
