Figure 14.2 shows a typical SMBus configuration. The SMBus interface will work at any voltage between 3.0V
and 5.0V and different devices on the bus may operate at different voltage levels. The SCL (serial clock) and SDA
(serial data) lines are bi-directional. They must be connected to a positive power supply voltage through a pull-up
resistor or similar circuit. When the bus is free, both lines are pulled high. Every device connected to the bus must
have an open-drain or open-collector output for both the SCL and SDA lines. The maximum number of devices on
the bus is limited only by the requirement that the rise and fall times on the bus will not exceed 300ns and 1000ns,
respectively.
