Chapter 27 Summary: Types of Loads In this chapter, the common types of loads are examined, as well as the parasitic elements that can affect the load at the input, such as parasitic capacitance, PN diode and the pair of input protection diodes that are intended to protect the input from over voltages. Readers will learn how the impedances of common logic device inputs compare to that of the transmission lines that provide their current. Previous Chapter | Next Chapter
