Low-Voltage Quad 2-Input OR Gate with 3.6-V Tolerant Inputs and Outputs

The TC74VCX32FT/FK is a high-performance CMOS 2-input
OR gate which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5V, 1.8V, 2.5V or 3.3V 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.

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 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).
