Using CD4081 AND Gate IC

To operate the AND gates on the CD4081 IC, start by connecting your power supply to the VDD and GND pins. The required voltage for the IC typically ranges from 3 to 15 volts.

Certain models of this IC can tolerate voltages up to 20 volts. For specific voltage requirements, always refer to the datasheet associated with your particular chip variant.

Inputs for the four AND gates on the IC are provided through the A and B pins. The inputs you provide here will determine the resulting output.

The outputs from the AND gates are outputted through the Q pins.

The CD4081 IC is a main component for executing AND gate functions in digital circuits. Here’s a straightforward way to use it:

• Power Setup - Connect the VDD and GND pins to a power source, typically between 3V and 15V. Check the datasheet for voltage compatibility to avoid damaging the IC.

• Inputs and Outputs - Hook up your inputs to the A and B pins. The IC outputs HIGH only when both inputs are HIGH.

• Building a Simple Circuit - For a basic demonstration, you'll need:

 - Two pushbuttons

 - A red LED

 - Three 10 kΩ resistors

 - The CD4081 IC

In this setup, the LED lights up only when both pushbuttons are pressed, showing a HIGH output from the AND gate.
