TC74LCX32F,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 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: VCC = 0 V
Note 3: High or low state. IOUT absolute maximum rating must be observed.
