Product Summary
The DM74LS138N is a Decoder. The DM74LS138N decodes one-of-eight lines, based upon the conditions at the three binary 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 with no external inverters, and a 32-line decoder requires only one inverter. An enable input can be used as a data input for demultiplexing applications.
Parametrics
DM74LS138N absolute maximum ratings : (1)Supply Voltage: 7V; (2)Input Voltage: 7V; (3)Operating Free Air Temperature Range: 0℃ to +70℃; (4)Storage Temperature Range: -65℃ to +150℃.
Features
DM74LS138N features: (1)LS138 3-to-8-line decoders incorporates 3 enable inputs to simplify cascading and/or data reception; (2)LS139 contains two fully independent 2-to-4-line decoders/demultiplexers; (3)Schottky clamped for high performance; (4)Alternate Military/Aerospace devices (54LS138,54LS139) are available.
