The contributions of supply current values for all four channels are combined at identical data rates.
The V
proportional to the data rate. Additional supply current associated with an individual channel operating at a given data rate can be calculated as described in the
Power Consumption
The power demands of the quiescent operation of the data channels was not separated from the power supply section. Efficiency includes the quiescent power
consumed by the I/O channels as part of the internal power consumption.
This current is available for driving external loads at the V
representing the maximum dynamic load conditions. Refer to the Power C

supply current is available for external use when all data rates are below 2 Mbps. At data rates above 2 Mbps, the data I/O channels draw additional current
section. The dynamic I/O channel load must be treated as an external load and included in the V
