Overview

MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14490 Hex Contact Bounce Eliminator The MC14490 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 digital contact bounce eliminator circuit takes an input signal from a bouncing contact and generates a clean digital signal four clock periods after the input has stabilized.
The bounce eliminator circuit will remove bounce on both the “make” and the “break” of a contact closure.
The clock for operation of the MC14490 is derived from an internal R–C oscillator which requires only an external capacitor to adjust for the des...
