OUTPUT DRIVE CURRENTS
Figure 20 shows typical I-V characteristics for the output drivers
of the ADSP-2184. The curves represent the current drive
capability of the output drivers as a function of output voltage.

POWER DISSIPATION
To determine total power dissipation in a specific application,
the following equation should be applied for each output:

V

×
f
C
= load capacitance,
f
= output switching frequency.
Example
In an application where external data memory is used and no
other outputs are active, power dissipation is calculated as follows:
Assumptions
External data memory is accessed every cycle with 50% of the
address pins switching.
External data memory writes occur every other cycle with
50% of the data pins switching.
Each address and data pin has a 10 pF total load at the pin.
The application operates at V
DD
= 5.0 V and t

= 25 ns.
