Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

74VHC139
Dual 2-to-4 Decoder/Demultiplexer
General Description
The VHC139 is an advanced high speed CMOS Dual 2-to4 Decoder/Demultiplexer fabricated with silicon gate
CMOS technology. It achieves the high speed operation
similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
The active LOW enable input can be used for gating or it
can be used as a data input for demultiplexing applications.
When the enable input is held HIGH, all four outputs are
fixed at a HIGH logic level independent of the other inputs.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply
and input voltages.
Features
■ High Speed: tPD = 5.0 ns (typ) at TA = 25°C
■ Low power dissipation: ICC = 4 µA (Max.) at TA = 25°C
■ High noise immunity: VNIH = VNIL = 28% VCC (Min.)
■ Power down protection is provided on all inputs
■ Pin and function compatible with 74HC139

74VHC139 Dual 2-to-4 Decoder/Demultiplexer
November 1992
74VHC139
Logic Symbols
Functional Description
The VHC139 is a high-speed dual 2-to-4 decoder/demultiplexer. The device has two independent decoders, each of
which accepts two binary weighted inputs (A0–A1) and provides four mutually exclusive active-LOW outputs (O0–O3).
Each decoder has an active-LOW enable (E). When E is
HIGH all outputs are forced HIGH. The enable can be used
as the data input for a 4-output demultiplexer application.
Each half of the VHC139 generates all four minterms of
two variables. These four minterms are useful in some
applications, replacing multiple gate functions as shown in
Figure 1, and thereby reducing the number of packages
required in a logic network.
