Input & Output Capacitance

[jogur]

Hi,

The datasheet of the ICs specify i/p & o/p capacitance. What does that actually mean. How is the load capacitance different from these capacitances?

Please clarify.

Thanks

hai,

i think these two capacitance are filter purpose.

Load capacitance - ussualy defined as max. load capacitance - is maximal capacitance, which can be driven by the pin(concerned with max pulse current of the pin).
Input and output capacitances - internal IC capacitances, this affects operation speed.

ip/op capacitancy exist between the gates when there is no load and load capacitancy comes from the applied load

input capacitance is the capacitance offered to the driving signal.
Output capacitance is the capability of the output driver i.e. if output capacitance is 50pF, it can drive a maximum of 5 loads of 10pF input capacitance.
