4 / 10 page  KA3846 4 Electrical Characteristics (VCC=15V, TA=0°C to + 70°C, unless otherwise specified) Notes : 1. Parameter measured at trip point at latch with V5 = VREF, V6 = 0V 2. RT = 10K Ω, CT = 4.7nF 3. Amplifier gain definde as: 4. Current into Pin 1 guaranteed to latch circuit in shutdown state. 5. Current into Pin 1 guaranteed not to latch circuit in shutdown state. 6. These parameters, although guaranteed over the recommended operating conditions, are not 100% tested in production. Parameter Symbol Conditions Min. Typ. Max.
