CD4025 Triple 3-Input NOR Gate – Datasheet

4,556 views

CD4025 consists of three NOR gates with 3 inputs and a single output. The IC is constructed by using the complementary MOS (CMOS) technology, integrated with p-type and n-type enhancement mode transistors. The IC is always available in a 14 – pin hermetically sealed dual in line package (DIP). The output of the IC always comes in TTL, which makes it easy to interface with other TTL, CMOS, and NMOS devices. The IC offers many features such as high noise immunity and low power dissipation. All inputs are protected against static discharge with diodes to VDD and VSS.

What is NOR Gate?

An OR gate followed by a NOT gate in a cascade is called a NOR gate. The inclusive NOR (Not – OR) gate has an output that is normally at logic level “1” and only goes “LOW” to a logic level “0” when any of its inputs are at logic level “1”. The Logic NOR Gate is the reverse or complementary form of the inclusive OR gate.

CD4025 Key Features

  • Wide supply voltage range 3.0V to 15V
  • High noise immunity 0.45 VDD (typ.)
  • 5V –10V parametric ratings
