TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74VCX14FT,TC74VCX14FK

Low-Voltage Hex Schmitt Inverter with 3.6-V Tolerant Inputs and Outputs

The TC74VCX14FT/FK is a high-performance CMOS schmitt
inverter which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5V, 1.8V, 2.5V or 3.3V systems, it achieves
high-speed operation while maintaining the CMOS low power
dissipation.

It is also designed with over-voltage tolerant inputs and
outputs up to 3.6 V.

Pin configuration and function are the same as the
TC74VCX04 but the inputs have hysteresis and with its schmitt
trigger function, the TC74VCX14 can be used as a line receivers
which will receive slow input signals.

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).
