TC74LCX126F/FT/FK  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74LCX126F,TC74LCX126FT,TC74LCX126FK  
Low-Voltage Quad Bus Buffer with 5-V Tolerant Inputs and Outputs  
The TC74LCX126 is a high-performance CMOS quad bus  
buffers. Designed for use in 3.3-V systems, it achieves high-speed  
TC74LCX126F  
operation while maintaining the CMOS low power dissipation.  
The device is designed for low-voltage (3.3 V) V  
applications,  
CC  
but it could be used to interface to 5-V supply environment for  
inputs.  
This device requires the 3-state control input (OE) to be set  
high to place the output into the high impedance state.  
All inputs are equipped with protection circuits against static  
discharge.

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 range (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).
