Figure 14-6. Two eight-bit encoders can be cascaded to handle 16 separate inputs. In this example, the encoders use active-high logic.

What Can Go Wrong

Problems that are common to all digital chips are summarized in the section on logic gates in “What Can Go Wrong”.

See “What Can Go Wrong” in the entry describing decoders for a list of more specific problems that also afflict encoders.

Chapter 15. decoder

In this Encyclopedia, a decoder is a digital chip that receives a binary-coded input and converts it to a decimal output by applying a logic state to one of a sequence of pins, each of which is assigned an integer value from 0 upward.

The term “decoder” also refers to components and devices that have other functions, such as decoding audio or video formats. These functions are not included here.
