Thanks for the reply.
As far as i understand from your last post, unless applied voltages doesn't exceed the recommended values of an input, or in other words, the voltage levels are compabitle, a current limiting resistor is unnecessary. Is that right? Or thats only true for CMOS inputs?
One more thing. I know that CMOS inputs sink very low amount of current at steady state, but they need a significant amount of current initially for charging their input capacitance. How can i make sure that the initial current requirement of this charging capacitor don't damage the output of my IC by exceeding its max. output current rating?
