* Adjust V_CC 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 defined as: G_V = ΔV_PIN1ΔV_PIN3(V_PIN3 = 0 to 0.8V)
4. Junction-to-air thermal resistance test environments
