... Also called “SSOP16”. 2002 Jan 04 programmable. The device can have addresses (determined by 2 address pins), so there can the NE1618 on the SMBus. It can also be put in a standby mode (in order to save power). This can be done either with software (over the SMBus) or with hardware (using the STBY pin) ...

... RESERVED 15H Power-on reset (POR) When the power is applied to the NE1618 while the device STDBY input pin is at low state, the device will enter into its power–on reset state and its registers are reset to their default values as shown in the Table 2 resulting in: Interrupt latch is cleared, the ALERT output driver is off and the ALERT pin is pulled to HIGH by an external pull-up resister ...

... A shielded twisted pair is recommended for a long distance remote sensor. Connect the shield of the cable at the device side to the NE1618 GND pin and leave the shield at the remote end unconnected to avoid ground loop. Also notice that the series resistance of the cable may introduce measurement error; ...
