3-Line-to-8-Line Decoders / Demultiplexers

The HD74LS138 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.
