3 / 14 page KA555 3 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 Parameter Symbol Conditions Min. Typ. Max.
