The TC74VHC125/126 are high speed CMOS QUAD BUS
BUFFERs fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Shottky TTL while maintaining the CMOS low power
dissipation.
The TC74VHC125 requires the 3-state control input G to be
set high to place the output into the high impedance state,
whereas the TC74VHC126 requires the control input G to be set
low to place the output into high impedance.
TC74VHC125FN, TC74VHC126FN
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V 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).
