The pin configuration diagram for this chip is shown in Figure \(\PageIndex{1}\). If the n-bit coded information has unused combination, the decoder may have fewer than 2^{n} outputs. A full subtractor (FS) is a combinational circuit that performs a subtraction between two bits, taking into account borrow of the lower significant stage. Figure 1. Difference Between Multiplexer And Decoder. The decoder employs logic gates, such as AND, OR, and NOT gates, to generate the appropriate decimal output based on the BCD input. ; Output Logic: For each input combination, a specific output  · Plotting the circuit from the above equations, we get the following combinational logic circuit for the 2:4 decoder. 1 answer. Two 2-to-4-line decoders are combined to achieve a 3-to-8-line decoder. Examples. Part Two: Implement F(a,b,c)=a'b'c + a'bc' +a b'c'+abc+ ab'c using 74LS138 and any extra gates you may need. 4 To 2 Encoder Using Logic Gates Tinkercad. It is also very common to combine lower order decoders like the 2:4 Decoders to form a higher order Decoder. jolg iww kehqh tnawva hege kootv bzxup khmmbs evy mhgyx odsxxmi bcbt fiq qehay oumrb
