**3 8 Decoder Logic Diagram**- The 238 decoder (in my case the 74HC238N) uses 3 selector inputs called A0, A1 and A2 which together can make 8 possible combinations (2^3=8) and thus has 8 outputs (0,1,2,3,4,5,6 and 7). In my tutorial I only use 5 of the outputs to turn on/off 5 LEDS.. Mar 28, 2010 · 3 : 8 Decoder using basic logic gates Here is the code for 3 : 8 Decoder using basic logic gates such as AND,NOT,OR etc .The module has one 3-bit input which is decoded as a 8-bit output. --libraries to be used are specified here. 3 TO 8 LINE DECODER (INVERTING) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology. LOGIC DIAGRAM This logic diagram has not be used to estimate propagation delays PIN No SYMBOL NAME AND FUNCTION 1, 2, 3 A, B, C Address Inputs.

cd74ac238 3-line to 8-line decoder/demultiplexer schs331 – february 2003 2 post office box 655303 • dallas, texas 75265 function table enable inputs select inputs outputs g1 g2a g2b c. lines) decoder with just four '238 ICs and one inverter. The '238 can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input and. I designed a 3:8 bit decoder for the final project of a digital logic course. This type of device would be used as a memory controller to minimize the number of input lines needed to access memory in a block of memory and anywhere else one wanted to minimize the number of input into a block..

Therefore 8 Boolean expressions are derived from Table 2.4.3, which will cause the decoder circuit to output logic 1 for these inputs. The Boolean equation needed for the design of an appropriate circuit will therefore contain these 8 Boolean expressions, and so will be long and complex.. Example : Construct a 3-to-8 decoder using two 2-to-4 deocders with enable inputs.Figure 6: Implementation of a 3-to -8 decoder without enable Decoder Expansion o It is possible to build larger decoders using two or more smaller ones. a 6-to-64 decoder can be designed with four 4-to-16 decoders and one 2-to-4 line decoder. ..
