NOTES:
1. All typical values are at VCC = 5V, TA = 25°C.
2. This is the supply current when each input is at least one of the specified TTL voltage levels rather than 0V or VCC.
3. For additional ICC information, see the following page.
NOTES:
1. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to absolute-maximum-rated conditions
for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded provided the input and output current ratings are observed.

Figure 1. Typical Characteristics: Supply vs Clock Frequency
CALCULATING POWER DISSIPATION
The ICC(f) current for the graph in Figure 1 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 ICC(f) taken from Figure 1, the maximum power dissipation (PT) of these FIFOs may be calculated by:
PT = VCC x [ICC(f) + (N x ΔICC x dc)] + Σ(CL x VCC
2
x fO)
where:
N = number of inputs driven by TTL levels
ΔICC = increase in power supply current for each input at a TTL HIGH level
dc = duty cycle of inputs at a TTL HIGH level of 3.4
CL = output capacitance load
fO = switching frequency of an output
When no reads or writes are occurring on these devices, the power dissipated by a single clock (CLKA or CLKB) input running at frequency fS is
calculated by:
PT = VCC x fS x 0.209 mA/MHz

NOTES:
1. Requirement to count the clock edge as one of at least four needed to reset a FIFO.
2. Only applies when serial load method is used to program flag Offset registers.
3. Skew time is not a timing constraint for proper device operation and is only included to illustrate the timing relationship between CLKA cycle and CLKB cycle.
4. Design simulated but not tested (typical values).
