SDP33 I2C voltage and IRQ trigger pin

we are evaluating the SDP33 sensor and have a few questions :
is the I2C rail running at 3v3 or 5v? ( the datasheet states a VDmax is 5.5V )
the connector exposed has 4 pins, so we assume that the IRQ pin from the sensor is not exposed, can you please confirm?


Yes the IRQ is not exposed. The level voltage of I2C bus is 3,3V.
