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 desired operating frequency (bounce delay). The clock may also be driven from an external clock source or the oscillator of another MC14490 (see Figure 5).
• Diode Protection on All Inputs
• Six Debouncers Per Package

• Single Line Input, Debounces Both “Make” and “Break” Contacts
• Does Not Require “Form C” (Single Pole Double Throw) Input
Signal
• Cascadable for Longer Time Delays
• Schmitt Trigger on Clock Input (Pin 7)
• Supply Voltage Range = 3.0 V to 18 V
• Chip Complexity: 546 FETs or 136.5 Equivalent Gates
