TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74ACT138P,TC74ACT138F,TC74ACT138FN,TC74ACT138FT
3-to-8 Line Decoder
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74ACT138 is an advanced high speed CMOS 3-to-8
LINE DECODER fabricated with silicon gate and double-layer
metal wiring C2MOS technology.
TC74ACT138P
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL 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.
When the device is enabled, 3 Binary Select inputs (A, B and
C) determine which one of the outputs ( Y0 - Y7 ) will go low.
TC74ACT138F
When enable input G1 is held low or either G2A or G2B is
held high, decoding function is inhibited and all outputs go high.
G1, G2A , and G2B inputs are provided to ease cascade
connection and for use as an address decoder for memory
systems.
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 should be
applied up to 300 mW.
