8.1 Overview. The SNx4HC138 devices are 3-to-8 decoders and demultiplexers. The three input pins, A, B, and C, select which output is active. The selected output is pulled LOW, while the remaining outputs are all HIGH. The conditions at the binary-select inputs at the three enable inputs select one of eight output lines.
