This article discusses How to Design a 4 to 16 Decoder using 3 to 8 Decoder, their circuit diagrams, truth tables and applications of decoder

2012年11月30日 · Simply wire the LEDs in a matrix, and each LED will only light when the "active-high-output" decoder is outputting high and the "active-low-output" decoder is outputting low.

4-to-16 decoder using 3-to-8 decoder (74138). A decoder is a combinational circuit that converts binary information from 'n' input lines to a maximum of 2 n unique output lines. If the n-bit coded information has unused or ‘don’t care’ combinations, the decoder may have fewer than 2 …

The 74HC154; 74HCT154 is a 4-to-16 line decoder/demultiplexer. It decodes four binary weighted address inputs (A0 to A3) to sixteen mutually exclusive outputs (Y0 to Y15). The device features two input enable (E0 and E1) inputs. A HIGH on either of …

The 4 to 16 decoder is the type of decoder which has 4 input lines and 16 (2 14) output lines. The functional block diagram of the 4 to 16 decoder is shown in Figure-6.

A 4 to 16 decoder is a digital circuit that converts a 4-bit binary input into a single active output line out of the 16 possible output lines. It uses the input binary value to select the corresponding output line.

PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 154 DESCRIPTION The M74HC154 is an high speed CMOS 4 TO 16 LINE DECODER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology.

2015年2月28日 · Since I am using two 3-8 decoders to develop a 4-to-16 decoder, I want to use 4 inputs out of the two 3-8 decoders. So I'll use all three of the first and the first of the second, and connect the last two inputs to ground, since they won't be used.

2023年8月15日 · The 4 to 16 decoder has 4 input lines that can represent 16 (2^4) unique binary numbers from 0000 to 1111. Depending on the specific 4-bit pattern at the input, the decoder activates one of the 16 output lines.

The 74HC/HCT154 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT154 decoders accept four active HIGH binary address inputs and provide 16 mutually exclusive active LOW outputs.
