Description

MC14490P - 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 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.

Features

  • Diode protection on all Inputs
  • Six debouncers per package
  • Internal pullups on all data Inputs
  • Can be used as a digital integrator, system synchroniser, or delay line
  • Internal oscillator or external clock source
  • TTL compatible data Inputs/Outputs
  • Single line Input, debounces both "make" and "break" contacts
  • Cascadable for longer time delays
