TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LVX157F,TC74LVX157FT
Quad 2-Channel Multiplexer
The TC74LVX157F/ FT is a high-speed CMOS quad 2-channel
multiplexer fabricated with silicon gate CMOS technology.
Designed for use in 3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation.
This device is suitable for low-voltage and battery operated
systems.
TC74LVX157F
This device consist of four 2-input digital multiplexers with
common select and strobe inputs. When the STROBE 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.
An input protection circuit ensures that 0 to 5 V can be applied
to the input pins without regard to the supply voltage. This
device can be used to interface 5V to 3V systems and two supply
systems such as battery back up. This circuit prevents device
destruction due to mismatched supply and input voltages.

Note: 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).
