2. General

General

The 74LCX14FT is a high-performance CMOS schmitt inverter. 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.

Pin configuration and function are the same as the 74LCX04FT but the inputs have hysteresis and with Schmitt

trigger function, the 74LCX14FT can be used as a line receivers which will receive slow input signals.

All inputs are equipped with protection circuits against static discharge.

Note: 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).
