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.
Ensure the capacitive load at the
output is ≤ 70 pF. This is not a hard limit, however it will ensure optimal
performance. This can be accomplished by providing short, appropriately sized
traces from the SN74HC00-Q1 to the receiving device.
Ensure the resistive load at the
output is larger than (VCC / IO(max)) Ω. This will ensure
that the maximum output current from the Section 5.1 is not violated.
Most CMOS inputs have a resistive load measured in megaohms; much larger than
the minimum calculated above.
Thermal issues are rarely a
concern for logic gates, however the power consumption and thermal increase can
be calculated using the steps provided in the application report, CMOS
