TC74HC125AP/AF Quad Bus Buffer
TC74HC126AP/AF Quad Bus Buffer
The TC74HC125A/126A are high speed CMOS QUAD BUS
BUFFERs fabricated with silicon gate C
2
MOS technology.
They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC125A requires the 3-state control input
G
to be
set high to place the output into the high impedance state,
whereas the TC74HC126A requires the control input to be set
low to place the output into high impedance.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

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).
Note 2: 500 mW in the range of Ta = 40 to 65°C. From Ta = 65 to 85°C a derating factor of 10 mW/°C shall be
applied until 300 mW.
