MC14490P

The MC14490P is one of the MC14490 series.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 MC14490P takes an input signal from a bouncing contact and generates a clean digital signal four clock periods after the input has stabilized.

Features of the MC14490P are:(1)wide supply voltage range:(1)Diode Protection on All Inputs; (2)Six Debouncers Per Package; (3)Internal Pullups on All Data Inputs; (4)Can Be Used as a Digital Integrator, System Synchronizer, or Delay Line; (5)Internal Oscillator (RC), or External Clock Source; (6)TTL Compatible Data Inputs/Outputs; (7)Single Line Input, Debounces Both "Make" and "Break" Contacts; (8)Does Not Require "Form C" (Single Pole Double Throw) Input Signal; (9)Cascadable for Longer Time Delays; (10)Schmitt Trigger on Clock Input (Pin 7); (11)Supply Voltage Range = 3.0 V to 18 V; (12)Chip Complexity: 546 FETs or 136.5 Equivalent Gates.

The absolute maximum ratings of the MC14490P can be summarized as:(1)DC Supply Voltage: 0.5 to + 18.0 V; (2)Input or Output Voltage (DC or Transient) : 0.5 to VDD + 0.5V; (3)Input Current (DC or Transient), per Pin :± 10 mA; (4)Power Dissipation, per Package: 500 mW; (5)Storage Temperature: 65 to + 150 ; (6)Lead Temperature (8Second Soldering) :260.If you want to know more information about MC14490P such as the electrical characteristics, please download the datasheet in www.seekic.com or www.chinaicmart.com.
