TC74VCX2125FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX2125FT,TC74VCX2125FK Low Voltage Quad Bus Buffer with 3.6-V Tolerant Inputs and Outputs The TC74VCX2125FT/FK is a high-performance CMOS quad bus buffer. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. This device requires the 3-state control input OE to be set high to place the output into the high-impedance state. The 26-Ω-series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge.

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).
