1. VDD = 2.7 to 5.5Vdc, VSS = 0 Vdc, TA = TL to TH, unless otherwise noted.
2. The IPULLUP (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 VOL (max) of the bus.
