What is an encoder design 8 to 3 line priority encoder?

Priority encoders are available in standard IC form and the TTL 74LS148 is an 8-to-3 bit priority encoder which has eight active LOW (logic “0”) inputs and provides a 3-bit code of the highest ranked input at its output.

What is an encoder explain the working of 8 to 3 encoder?

The 8 to 3 Encoder or octal to Binary encoder consists of 8 inputs : Y7 to Y0 and 3 outputs : A2, A1 & A0. Each input line corresponds to each octal digit and three outputs generate corresponding binary code.

How do you make a 3/8 decoder?

3 Line to 8 Line Decoder Block Diagram This decoder circuit gives 8 logic outputs for 3 inputs and has a enable pin. The circuit is designed with AND and NAND logic gates. It takes 3 binary inputs and activates one of the eight outputs. 3 to 8 line decoder circuit is also called a binary to an octal decoder.

Which of the following can be used to construct the 3/8 line decoder?

The implementation of this 3 line to 8 line decoder can be done using two 2 lines to 4 line decoders. We have discussed above that 2 to 4 line decoder includes two inputs and four outputs. So, in 3 lines to 8 line decoder, it includes three inputs like A2, A1 & A0 and 8 outputs from Y7 – Y0.

What is the use of 3 to 8 decoder?

3 to 8 line decoder demultiplexer is a combinational circuit that can be used as both a decoder and a demultiplexer. IC 74HC238 decodes three binary address inputs (A0, A1, A2) into eight outputs (Y0 to Y7). The device also has three Enable pins. The same combination is used as a demultiplexer.

How many and gates are required to implement a 3 to 8 decoder with an enable?

three NOT gates
From the above Boolean expressions, the implementation of 3 to 8 decoder circuit can be done with the help of three NOT gates & 8-three input AND gates. In the above circuit, the three inputs can be decoded into 8 outputs, where every output represents one of the midterms of the three input variables.
