DESCRIPTION
The M54/74HC139 is a high speed CMOS DUAL
TWO LINE TO FOUR LINE DECODER/DEMULTI-
PLEXER fabricated insilicon gate C
2
MOS technol-
ogy. It has the same high speed performance of
LSTTL combined with true CMOS low power con-
sumption. The active low enable input can be used
for gating or as a data input for demultiplexing ap-
plications. While the enable input is held high, all
four outputs are high independently of the other in-
puts. Allinputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
