74AHC139; 74AHCT139
Dual 2-to-4 line decoder/demultiplexer
Rev. 02 — 9 May 2008
Product data sheet
1. General description
The 74AHC139; 74AHCT139 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7-A.
The 74AHC139; 74AHCT139 is a high-speed, dual 2-to-4 line decoder/demultiplexer. This
device has two independent decoders, each accepting two binary weighted inputs (nA0
and nA1) and providing four mutually exclusive active LOW outputs (nY0 to nY3). Each
decoder has an active LOW enable input (nE). When nE is HIGH, every output is forced
HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer
application.
The 74AHC139; 74AHCT139 is identical to the HEF4556 of the HE4000B family.
2. Features
I Balanced propagation delays
I All inputs have Schmitt-trigger actions
I Inputs accept voltages higher than VCC
I Input levels:
N For 74AHC139: CMOS level
N For 74AHCT139: TTL level
I ESD protection:
N HBM EIA/JESD22-A114E exceeds 2000 V
N MM EIA/JESD22-A115-A exceeds 200 V
N CDM EIA/JESD22-C101C exceeds 1000 V
I Multiple package options
I Specified from −40 °C to +85 °C and from −40 °C to +125 °C

[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL
.
[3] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
