Either north or south pole of sufficient strength will turn the output
on. The output will be turned off under no magnetic field. While
the magnetic flux density (B) is larger than operating point (Bop),
the output will be turned on (low), the output is held until B is
lower than release point (Brp), then turned off.
Good RF noise immunity
-40°C to 85°C operating temperature
