OUTPUT DRIVE CURRENTS
Figure 38 through Figure 52 show typical current-voltage char-
acteristics for the output drivers of the ADSP-BF51xF
processors.
The curves represent the current drive capability of the output
drivers. See Table 7 on Page 17 for information about which
driver type corresponds to a particular ball.
