1. Functional Description
•
Dual 2-to-4 Line Decoder
2. General
The 74VHC139FT is an advanced high speed CMOS 2 to 4 LINE DECODER/DEMULTIPLEXER fabricated with
silicon gate C2MOS 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 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).
Note 1: 180 mW in the range of T

.
From T

a derating factor of -3.25 mW/ shall be
applied until 50 mW.
