Inverting and non-inverting CML-compatible differential outputs from the driver. Nominal
differential output impedance = 100 Ω.
(1) I = Input, O = Output and 2.5-V LVCMOS pins are 2.5-V levels only.
Only SMBus pins SDA and SDC and INT pin are 3.3-V tolerant. These three pins are open-drain and require external pullup resistors.
