DESCRIPTION
The M54/74HCT139 is a high speed CMOS DUAL
TWO LINE TO FOUR LINE DECODER/DEMULTIPLEXER fabricated in silicon gate C2MOS technology. It has the same high speed performance of
LSTTL combined with true CMOS low power consumption. The active low enable input 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. All
inputs are equipped with protection circuits against
static discharge and transient excess volt-age.This integrated 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

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/2 (per decoder)
