SN74HCT139 Dual 2-to-4 Line Decoders/Demuxes

Texas Instruments SN74HCT139 Dual 2-to-4 Line Decoders/Demultiplexers are made of two individual 2-line to 4-line decoders in a single package. The active-low enable (G) input can be used as a data line in demultiplexing applications. The Texas Instruments SN74HCT139 decoders/demultiplexers feature fully buffered inputs, representing only one normalized load to its driving circuit.
