Dual 2-to-4 Line Decoder
The TC74VHC139 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.
Features
High speed: tpd = 5.0 ns (typ.) at VCC = 5 V
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.
Balanced propagation delays: tpLH tpHL
Wide operating voltage range: VCC (opr) = 2 V to 5.5 V
Pin and function compatible with 74ALS139

Absolute Maximum Ratings (Note)
Characteristics Symbol Rating Unit
Supply voltage range VCC 0.5 to 7.0 V
DC input voltage VIN 0.5 to 7.0 V
DC output voltage VOUT 0.5 to VCC + 0.5 V
Input diode current IIK 20 mA
Output diode current IOK ±20 mA
DC output current IOUT ±25 mA
DC VCC/ground current ICC ±75 mA
Power dissipation PD 180 mW
Storage temperature Tstg 65 to 150 °C
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).
