Add a decoupling capacitor
from VCC to GND. The capacitor needs to be placed physically
close to the device and electrically close to both the VCC and
GND pins. An example layout is shown in the Layout section.
Ensure the capacitive load at
the output is ≤ 50 pF. This is not a hard limit; it will, however, ensure
optimal performance. This can be accomplished by providing short,
appropriately sized traces from the SN74LV8T245-Q1
to one or more of the receiving devices.
Ensure the resistive load at
the output is larger than (VCC / IO(max)) Ω. This will
ensure that the maximum output current from the Absolute Maximum
Ratings is not violated. Most CMOS inputs have a resistive load
measured in MΩ; much larger than the minimum calculated previously.
Thermal issues
are rarely a concern for logic gates; the power consumption and thermal
increase, however, can be calculated using the steps provided in the
application report, CMOS Power Consumption and Cpd
Calculation.
