Low: transistor open (VCE < 1 V).
High: transistor closed (VCE > 4 V).
Higher magnetic fields could cause irreversible shifts of parameters.
Output pins are designed for electrostatic sensitivity with field strengths up to 2 kV according to Human Body
Model (HBM), MIL-STD-883, Method 3015.
MR pins are designed for electrostatic sensitivity with field strengths up to 0.3 V according to Human Body
Model (HBM), MIL-STD-883, Method 3015.
