An ohm is an ohm, right? Not so fast — there are many different types of resistors. To insure that your circuit works and stays working, use the right type of resistor. In this article, you'll learn about the common types of resistors and their special characteristics.
Modern digital logic ICs are widely available in three basic types: TTL devices, “slow” CMOS devices, and “fast” CMOS devices. Each of these families has its own particular advantages and disadvantages, and its own special set of usage rules. This four-part mini-series explains the basic principles and usage rules of each, and provides practical usage guidance for the vast range of ICs available in each of these families. This opening article concentrates on digital logic IC basics.
