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 activelow enable input can beused for

gating or as a data input for demultiplexing applica-

tions. While theenable input is held high, all four out-

puts are high independently of the other inputs. All

inputs are equipped with protection circuits against

staticdischarge and transient excessvolt-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
