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 RC 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).
NOTE: Immediately after powerup, the outputs of the MC14490 are in
indeterminate states.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be
taken to avoid applications of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation, Vin and Vout
should be constrained to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
