Are there any regulations for the capacitance of the capacitor attached to the output terminal of a general-purpose logic IC?

If a large capacitor (capacitive load) is connected to the general-purpose logic IC, there is a possibility of malfunction due to the charge/discharge current that flows when the output mode transitions (H⇒L, L⇒H). It is recommended to keep the capacitor connected to the output pin to 500 pF or less, as there is a possibility that a current exceeding the specified value may flow through the output parasitic diode due to discharge. For loads higher than that, limit the discharge current via resistors as shown in Fig. 1 Please note that in this case, a delay occurs in the output signal.

Devices without an input-tolerant function such as the TC4000 and TC74HC/AC series should not also drive a large capacitive load because current could flow through the input protection diode if the power-off time is short.
It is recommended to keep the load capacitance connected to an input pin below 500 pF. If it is exceeded, insert a resistor as shown in Fig. 2 Note that there will also be a delay in the input signal in this case.
