The TC74VHCT125A/126A 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 TC74VHCT125A requires the 3-state control input G to
be set high to place the output into the high impedance state,
whereas the TC74VHCT126A requires the control input G to be
set low to place the output into high impedance.
The input voltage are compatible with TTL output voltage.
This device may be used as a level converter for interfacing
3.3 V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can
be applied to the input and output (Note) pins without regard to
the supply voltage. There structure prevents device detsruction
due to mismatched supply and input/output voltages such as
battery back up, hot board insertion, etc.

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).
