DESCRIPTION

The M54/74HC139 is a high speed CMOS DUAL
TWO LINE TO FOUR LINE DECODER/DEMULTI­PLEXER fabricatedin silicon gate C2MOS technol­ogy. It has the same high speed performance of
LSTTL combined with true CMOS low power con­sumption.The activelow enableinput can be used
for gating or as a data input for demultiplexing ap­plications. While the enable input is held high, all
four outputs are high independently of the other in­puts.Allinputs are equipped with protectioncircuits
against static discharge and transient excess volt­age.
