Not measured in production. 6. InH=bus current at DnH, InL=bus current at DnL 7. VDnD=VDnH-VDnL 8. Max VDnD = VSUPn - 2 * VMID_OFFSET - VDnD(Drop), VMID_OFFSET = |VMID - VSUPn / 2| 9. Worst Case Disabled Low Side Bus Leakage for DnL occurs with DnL = VSUP and DnH = 0V. In this configuration, the DnL leakage current can exceed 1mA. This is not measured in production. Table 3. Static Electrical Characteristics (continued) Characteristics noted under conditions 4.75V ≤ VCC ≤ 5.25V, 9.0V ≤ VSUPn ≤ 25V,-40°C ≤ TA ≤ 90°C, unless otherwise noted. Voltages relative to GND, unless otherwise noted. Typical values noted reflect the approximate mean values of the parameter at TA = 25°C under nominal conditions, unless otherwise noted.
