Electrical Characteristics (Continued)
(VCC = 15V, RT = 10kΩ, CT = 3.3nF, TA = 0°C to +70°C, Unless otherwise specified)
* Adjust VCC above the start threshold before setting at 15V
Notes :
1. These parameters, although guaranteed, are not 100% tested in production.
2. Parameter measured at trip point of latch with V2 = 0V.
3. Gain def ine d as: G V = ∆VPIN1∆VPIN3(VPIN3 = 0 to 0.8V)
4. Junction-to-air thermal resistance test enviroments.
