3-Line-to-8-Line Decoders / Demultiplexers
The SD74LS138E decodes one-of-eight line dependent on the conditions at the three binaly select inputs and the three enable inputs. Two active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented without external inverters and a 32-line decoder requires only one inverter. An enable input can be used as a data input for demultiplexing applications.
