All parameters specified at TA = -40°C to +85°C unless otherwise noted.
These parameters guaranteed by design and characterization.
Human Body Model per MIL-STD-883, Method 3015, CDischarge = 100pF, RDischarge = 1.5KΩ, VN grounded.
Standard IEC 61000-4-2 with CDischarge = 150pF, RDischarge = 330Ω, VN grounded.
These measurements performed with no external capacitor on PinX.
