Dual 2-to-4 Line Decoder

The TC74HCT139A is a high speed CMOS 2-to-4 LINE

DECODER/DEMULTIPLEXER fabricated with silicon gate

C2MOS technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

This device may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

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 “H”, all four outputs are fixed at

a high logic level independent of the other inputs.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• High speed: tpd = 17 ns (typ.) at VCC = 5 V

• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C

• Compatible with TTL outputs: VIH = 2 V (min)

IL = 0.8 V (max)

• Wide interfacing ability: LSTTL, NMOS, CMOS

• Output drive capability: 10 LSTTL loads

• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)

• Balanced propagation delays: tpLH ∼

−

tpHL

• Pin and function compatible with 74LS139

Pin Assignment

Note: xxxFN (JEDEC SOP) is not available in

Japan.

Absolute Maximum Ratings (Note 1)

Characteristics Symbol Rating Unit

Supply voltage range VCC −0.5~7 V

DC input voltage VIN −0.5~VCC + 0.5 V

DC output voltage VOUT −0.5~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 ±50 mA

Power dissipation PD 500 (DIP) (Note 2)/180 (SOP) mW

Storage temperature Tstg −65~150 °C

Note 1: 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 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be

applied until 300 mW.
