# What is decoder IC number?

## What is decoder IC number?

The Integrated Circuit is of 16 pins. We have three input pins which are actively in high state and are classified as I2, I1 and I0. The outputs are actively in low state and are eight in number and are classified as O7*, O6*, …, O0*. A power supply of +5 V DC is needed by the chip and is Grounded.

What is the IC number for encoder?

ENCODE AND DECODER CIRCUIT USING IC 74138 and 74148. AIM: To verify the operation of 8 to 3 line Encoder and 3 to 8 Decoder using IC 74138 and 74148.

Which IC is used in decoder and encoder?

Both encoder and decoder are combinational circuits as their output depends only on current values of the input. In this tutorial, the encoder and decoder circuits will be constructed using 7400 Series ICs.

### What is encoder and decoder definition?

An encoder/decoder is a hardware tool that interprets information and converts it into a code, while also possessing the ability to convert that code back to its original source. In computing, an encoder takes either a sequence of characters or an analog signal and formats it for efficient transmission and/or storage.

What is decoder and its types?

Basically, Decoder is a combinational logic circuit that converts coded input to coded outputs provided both of these are different from one another. The name decoder means translating of coded information from one format into another. So the input code generally has fewer bits than output code word.

What encoder means?

Simply put, an encoder is a sensing device that provides feedback. Encoders convert motion to an electrical signal that can be read by some type of control device in a motion control system, such as a counter or PLC. The encoder sends a feedback signal that can be used to determine position, count, speed, or direction.

#### What is decoder function?

A decoder is a device that generates the original signal as output from the coded input signal and converts n lines of input into 2n lines of output. An AND gate can be used as the basic decoding element because it produces a high output only when all inputs are high.

Which of the following is a decoder IC?

5. Which of the following is a decoder IC? Explanation: 8870 is a DTMF decoder circuit, which decodes DTMF tune and produces corresponding output.

What do you mean by decoder?

Definition of decoder : one that decodes especially : an electronic device that converts signals from one form to another (as for unscrambling a television transmission)

## What is electronic decoder?

A decoder is a circuit that changes a code into a set of signals. It is called a decoder because it does the reverse of encoding, but we will begin our study of encoders and decoders with decoders because they are simpler to design.
