Low-Voltage Quad 2-Input AND Gate with 5-V Tolerant Inputs and Outputs
The TC74LCX08 is a high-performance CMOS 2-input AND
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
CC
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).
