CD4490 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4490 has Hex contact bounce eliminator
CD4490 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
CD4490 Features
- Internal Oscillator (R–C), or External Clock Source
- TTL Compatible Data Inputs/Outputs
- 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
