CALCULATING POWER DISSIPATION
The I
CC
(f) current for the graph in Figure 16 was taken while simultaneously reading and writing the FIFO on the IDT723641
with CLKA and CLKB set to fS. All data inputs and data outputs change state during each clock cycle to consume the highest
supply current. Data outputs were disconnected to normalize the graph to a zero-capacitance load. Once the capacitance
load per data-output channel and the number of IDT723631/723641/723651 inputs driven by TTL HIGH levels are known,
the power dissipation can be calculated with the equation below.
With I
CC
(f) taken from FIgure 16, the maximum power dissipation (PT) of the IDT723631/723641/723651 may be
calculated by:

where:
N

number of inputs driven by TTL levels
I
CC
=

dc
=
duty cycle of inputs at a TTL HIGH level of 3.4
C
L

f
O
=
switching frequency of an output
When no reads or writes are occurring on the IDT723631/723641/723651, the power dissipated by a single clock (CLKA
or CLKB) input running at frequency fS is calculated by:
