I need a part similar to a 74HC148 8:3 encoder, but which takes 32 input lines and encodes them to a 5 bit value. Feb 10, 2023 · Construct a 5-to-32-line decoder with four 3-to-8-line decoders with enable and a 2-to-4-line decoder. I can guarantee that only one of the 32 will be high at a time, so I don't even need the priority feature although it would be a plus. The eight disk positions can be decoded with a 3-bit binary decoder with the appropriate assignment of signals to the decoder outputs, as shown in Figure 3. F= XYZ + (\overline We would like to show you a description here but the site won’t allow us. The 2-to-4 decoder enables one of the 3-to-8 decoders based on the input selection. 4.
