Absolute maximum ratings:
Maximum voltage on input pin1 with respect to pin6: 3V
Minimum voltage on input pin1 with respect to pin6: 0V
The input is protected from short positive or negative ESD transients
This input is designed for connecting sensors with passive output (not outputting voltage) such as:
Passive infrared (PIR) sensors for motion detection (sensors with open
collector or relay output are suitable type to use )
