TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HCT139AP,TC74HCT139AF,TC74HCT139AFN
Dual 2-to-4 Line Decoder
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74HCT139A is a high speed CMOS 2-to-4 LINE
DECODER/DEMULTIPLEXER fabricated with silicon gate
C2MOS technology.
TC74HCT139AP
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.
TC74HCT139AF
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

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.
