OUTPUT DRIVE CURRENTS

Figure 28 through Figure 33 show typical current voltage char-

acteristics for the output drivers of the transceiver. The curves

represent the current drive capability of the output drivers as a

function of output voltage. Drive strength 0 is DS0, and drive

strength 1 is DS1.

Note the following:

•I2C pins only support high drive strength (DS1).

• Digital I/Os include ADR1, ADR2, SCK, MISO, MOSI,

SIOn, BCLK, SYNC, IRQ, and GPIO7 pins.
