ADSP-BF592
OUTPUT DRIVE CURRENTS
Figure 25 through Figure 33 show typical current-voltage char-
acteristics for the output drivers of the ADSP-BF592 processor.
The curves represent the current drive capability of the output
drivers. See Table 7 on Page 14 for information about which
driver type corresponds to a particular pin.
