Product Summary
The MC14490P is a type of digital contact bounce eliminator which is constructed with complementary MOS enhancement mode devices, and is used for the elimination of extraneous level changes that result when interfacing with mechanical contacts. The MC14490P circuit takes an input signal from a bouncing contact and generates a clean digital signal four clock periods after the input has stabilized.
