CD4174-Hex Type D Flip-Flop


CD4174 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4174 has a Hex Type D Flip-Flop

CD4174 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.

CD4174 Features

  • Static Operation
  • All Inputs and Outputs Buffered
  • Diode Protection on All Inputs
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc
  • Capable of Driving Two Low–Power TTL Loads or One Low–Power Schottky TTL Load Over the Rated Temperature Range
