4. DIGITAL LOGIC FAMILIES. 4.1. INTRODUCTION. The switching characteristics of semiconductor devices have been discussed in Chapter 3. Basically, there are two types of semiconductor devices: bipolar and unipolar. Based on these devices, digital integrated circuits have been made which are commercially available.
In this module, the differences and similarities between the various families of logic ICs available are described, along with their important operating conditions. Logic 1 and Logic 0 are a bit more complex that 5V and 0V because these digital ICs are really little analogue circuits posing as 'Digital'. A sort of sheep in wolves

Digital Electronics. 2. TTL families. 1 Introduction. In this module, we will discuss about the bipolar logic family TTL. We begin with the basics of. TTL and understand the working of the basic building block of the family NAND gate. TTL logic gate has totem pole arrangement at the output of the circuit. There are two variations
The first logic circuit was developed using discrete circuit components. Using advance techniques, these complex circuits can be miniaturized and produced on a small piece of semiconductor material like silicon. Such a circuit is called integrated circuit (IC). Now-a-days, all the digital circuits are available in IC form.
