ADSP-BF504/ADSP-BF504F/ADSP-BF506F
PROCESSOR—OUTPUT DRIVE CURRENTS
Figure 32 through Figure 40 show typical current-voltage char-
acteristics for the output drivers of the ADSP-BF50xF
processors.
The curves represent the current drive capability of the output
drivers. See Table 11 on Page 21 for information about which
driver type corresponds to a particular ball.
