The Allegro A3144 Hall Effect Switch has an "open collector" output.  It is designed to sink current (up to 25 mA) when in the ON state.  This is different from a Hall sensor that is designed to produce, say, a +5V or 0V output when switched. It also has considerable hysteresis, and has output rise and fall times between about 0.2 and 2 microseconds.

You may wish to consider how an open-collector device is meant to perform in a circuit.
