TC74LCX32F/FN/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX32F,TC74LCX32FN,TC74LCX32FT,TC74LCX32FK Low-Voltage Quad 2-Input OR Gate with 5-V Tolerant Inputs and Outputs The TC74LCX32 is a high-performance CMOS 2-input OR gate. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low-power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for inputs. All inputs are equipped with protection circuits against static discharge. Note: xxxFN (JEDEC SOP) is not available in Japan.

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).
