CMOS Handling Precautions- Precautions for Handling CMOS Devices

Electrostatic Discharge

Complementary metal oxide semiconductors must be handled with care. CMOS safety precautions will extend the life of your equipment. If you do not follow these precautions when you are working with circuits that contain complementary metal oxide semiconductors, you may lose some of your investment.

Each CMOS device that you work with is sensitive to electrostatic charges. If all of the inputs on the device that you are working with are not in use, you should take action to ensure that those that are not occupied do not attract an electrostatic charge.

Electrostatic Induction

The easiest way to prevent unused inputs on CMOS devices from getting an electrostatic charge is to ground them. If you don’t ground the inputs, you won’t be able to control what happens with your system. At any time, the inputs you aren’t using could have a higher charge than you predict and this could interfere with your system.

The sensitivity of CMOS devices requires that they are shipped in special packaging. Whenever you get a new CMOS device, you should avoid touching the pins. When you unwrap a new complementary metal oxide semiconductor, you should place it on a surface that is already grounded. Never place it on any surface that might carry a charge.
