TC74VCX157FT/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VCX157FT, TC74VCX157FK
Low Voltage Quad 2-Channel Multiplexer with 3.6 V Tolerant Inputs and Outputs
The TC74VCX157 is a high performance CMOS multiplexer
which is guaranteed to operate from 1.2-V to 3.6-V. Designed for
TC74VCX157FT
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.
It consists of four 2-input digital multiplexers with common
select and strobe inputs.
When the ST input is held “H” level, selection of data is
inhibited and all the outputs become “L” level. The SELECT
decoding determines whether the A or B inputs get routed to
their corresponding Y outputs.
TC74VCX157FK
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).
