Quad Bus Buffer
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74LVX125F/ FN/ FT is a high-speed CMOS quad bus
buffer fabricated with silicon gate CMOS technology. Designed
TC74LVX125F
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.
This device requires the 3-state control input G to be set high
to place the output into the high-impedance.
An input protection circuit ensures that 0 to 5.5V 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).
