CD4560-NBCD adder


CD4560 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4560 has an NBCD adder

CD4560 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.

CD4560 Features

  • Very Low Quiescent Current
  • High Noise Immunity
  • Single Supply Operation – Positive OR Negative
  • Supply Voltage Range 3V TO 18V
  • Diode Protection on all Inputs
