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) V

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.

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).
