TC74VCX138FT/FK
TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC74VCX138FT, TC74VCX138FK
Low Voltage 3-to-8 Line Decoder with 3.6 V Tolerant Inputs and Outputs
The TC74VCX138 is a high performance CMOS 3-to-8 decoder
which is guaranteed to operate from 1.2-V to 3.6-V. Designed for
use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed
operation while maintaining the CMOS low power dissipation.
It is also designed with over voltage tolerant inputs and
outputs up to 3.6 V.
When the device is enabled, 3 binary select inputs (A, B and C)
determine which one of the outputs (Y0 - Y0) will go low.
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.

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: VCC = 0 V
Note 3: High or low state. IOUT absolute maximum rating must be observed.
