DESCRIPTION
The M54/74HCT139 is a high speed CMOS DUAL
TWO LINE TO FOUR LINE DECODER/DEMULTI-
PLEXER fabricated in silicon gate C2MOS 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 applica-
tions. While the enable input is held high, all four out-
puts are high independently of the other inputs. All
inputs are equipped with protection circuits against
static discharge and transient excess volt-age.This in-
tegrated circuit has input and output characteristics
that are fully compatible with 54/74 LSTTL logic
families. M54/74HCT devices are designed to directly
interface HSC2MOS systems with TTL and NMOS
components. They are also plug in replacements for
