SBOS854E March 2018 – August 2021 TMP1075
The recommended value for the pullup resistor is 5 kΩ. In some applications, the pullup resistor can be lower or higher than 5 kΩ, but the maximum current through the pullup current is recommended to not exceed 3 mA on the SCL and SDA pins. The SCL, SDA, A0, and A1, lines can be pulled up to a supply that is higher than V+. The ALERT line can be pulled up to a supply higher than V+ on the TMP1075 non-N orderables. The A2 pin can only be connected to GND or V+. When the ALERT pin is not used, it can either be connected GND or left floating.
