1. V_DD = 2.7 to 5.5Vdc, V_SS = 0 Vdc, T_A = T_L to T_H, unless otherwise noted.
2. The I_PULLUP (max) specification is determined primarily by the need to accommodate a maximum of 1.1kΩ equivalent se-
ries resistor of removable SMBus devices, such as the smart battery, while maintaining the V_OL (max) of the bus.
