NOTES:
1. All voltages are referenced to ground.
2. Internal heating caused by O.S. loading will cause the DS75 to read approximately 0.5
°C higher if
O.S. is sinking the max rated current.
3. IDD specified with O.S. pin open.
4. IDD specified with VDD at 5.0V and SDA, SCL = 5.0V, 0°C to 70°C.
5. See Timing Diagram in Figure 2. All timing is referenced to 0.9 x VDD and 0.1 x VDD.
6. After this period, the first clock pulse is generated.
7. For example, if CB = 300pF, then tR[min] = tF[min] = 50ns.
