**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.

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. ..
