is required. θ V JA and θJC are specified for a device soldered on a DD to GND −0.3 V to +7 V JEDEC 4-layer test board for surface-mount packages with SDA Voltage to GND −0.3 V to VDD + 0.3 V 16 thermal vias. The values listed in Table 4 are based on SCL Output Voltage to GND −0.3 V to VDD + 0.3 V simulated data. A0 Input Voltage to GND −0.3 V to VDD + 0.3 V A1 Input Voltage to GND −0.3 V to VDD + 0.3 V
