Question 1: Draw the function table of 3 to 8 decoder.
Answer:
THE 74XX138 3-TO-8 DECODER
The 3-to-8, 74XX138 Decoder is also commonly used in logical circuits. Similar, to the 2-to-4 Decoder, the 3-to-8 Decoder has active-low outputs and three extra NOT gates connected at the three inputs to reduce the four unit load to a single unit load. The 3-to-8 Decoder has three enable inputs, one of the three enable inputs is active-high and the remaining two are active-low. All three enable inputs have to be activated for the Decoder to work. The function table of the 3-to-8 decoder is presented. Table 17.1
