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
email any questions regarding the system integration to

74VHC138 3-to-8 Decoder/Demultiplexer

74VHC138
3-to-8 Decoder/Demultiplexer
General Description
The VHC138 is an advanced high speed CMOS 3-to-8
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.
When the device is enabled, 3 binary select inputs (A
0
, A
1
and A
2
) determine which one of the outputs (O
0
–O
7
) will go
LOW. When enable input E
3
is held LOW or either E
1
or E
2
is held HIGH, decoding function is inhibited and all outputs
go HIGH. E
3
, E
1
and E
2
inputs are provided to ease cas-
cade connection and for use as an address decoder for
memory systems. An input protection circuit ensures that
0V to 7V can be applied to the input pins without regard to
the supply voltage. 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.

Note 1:
Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside databook specifica-
tions.
Note 2:
Unused inputs must be held HIGH or LOW. They may not float.
