... These allow the user to choose weaker DC pull-up currents on the bus, reducing power consumption while still meet- ing system rise-time requirements. During positive bus transitions, the LTC4300A-3 switches in 2mA (typical) of current to quickly slew the SDA and SCL lines once their DC voltages exceed 0.6V. Using a general rule of 20pF of ...
