The input circuitry is compatible with 3.3 and 5 V microcontrollers. The concept of the input pin is to react to voltage
thresholds. An implemented Schmidt trigger avoids any undefined state if the voltage on the input pin is slowly
increasing or decreasing. The output is either OFF or ON but cannot be in a linear or undefined state. The input
circuitry is compatible with PWM applications.
pin is not needed, it must be left opened, or must be connected to device ground (and not module ground) via a
4.7kΩ input resistor.

The DEN / DSEL pins enable and disable the diagnostic functionality of the device. The pins have the same
structure as the Input pins, please refer to
8.3
The IN, DSEL and DEN use a comparator with hysteresis. The switching ON / OFF takes place in a defined region,
set by the thresholds
and depends on the process, as well as the temperature. To avoid cross talk and parasitic turn ON and OFF, a
hysteresis is implemented. This ensures a certain immunity to noise.
