Input circuitry
The input circuitry is compatible with 3.3 V and 5 V microcontrollers. The concept of the input pin is to react to
voltage thresholds. An implemented Schmitt 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. Figure 28 shows the electrical equivalent input circuitry. In
case the pin is not needed, it must be leꢀ opened, or must be connected to device ground (and not module
ground) via a 10 kΩ input resistor.

DEN / DSEL0, 1 pin
The DEN / DSEL0, 1 pins enable and disable the diagnostic functionality of the device. The pins have the same
structure as the INput pins, please refer to Figure 28.
8.3
Input pin voltage
The IN, DSEL and DEN use a comparator with hysteresis. The switching ON / OFF takes place in a defined region,
set by the thresholds VIN(L) Max. and VIN(H) Min. The exact value where the ON and OFF take place are unknown
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.
